What should buyers read before sending an RFQ?

The RFQ checklist, production process, material selection and finishing guides help buyers prepare drawings and requirements before quote review.

Do these resources replace engineering review?

No. The resources help buyers prepare better information, but drawings, material, finish, tolerance and quantity still need project-specific engineering review.

Which guide is best for a new stamping project?

Start with the RFQ checklist and process guide, then review material and finishing pages if the drawing already includes those requirements.

Can I send drawings if I am not sure about the process?

Yes. Early drawings, photos or samples can be reviewed to decide whether the part fits stamping, fabrication, tooling development or another route.

Metal Stamping Resources for RFQ, DFM and Production Review

ANGLE BRACKET SELECTIONAngle Bracket Selection: Dimensions, Holes and Corner ConnectionsFor a custom angle bracket enquiry, start with the two parts it must connect. Show the mounting faces, available space and hole locations, then identify material, finish and quantity requirements. A sketch or marked photograph can begin the discussion before every detail is settled.

FINISH INSPECTIONSurface Finish Inspection: Common Problems on Delivered Metal PartsA shipment of finished metal parts should be checked against the approved drawing, finish specification and sample. When you find a colour mismatch, damaged coating or a tight assembly, first identify the affected locations and the requirements they must meet. Keep appearance, coating integrity, corrosion testing and finished fit as separate decisions.

BRACKET REINFORCEMENTSheet Metal Gussets: Reinforcing Ribs at a Bracket BendSpecifying a bent bracket with a reinforcing rib starts with its mounting arrangement. Share the drawing or a marked-up photo, identify the fixed face and show where the load acts. Those details make the gusset geometry, clearance and sample checks meaningful before tooling is agreed.

METAL FINISHINGZinc, Nickel or Chrome Plating? Choose the Coating Around the Part’s JobChoose a plating system around protection, appearance, wear and finished fit. Compare the complete layers and sample requirements for the same part.

CUSTOM ANTENNA TERMINALSPhosphor Bronze Antenna Terminals: Dimensions and Drawing ReviewThis phosphor bronze antenna terminal has a specified sheet thickness of 0.5 mm and outside diameter of 18.9 mm. For a custom part project, send HARVLAND the part drawing or sample photographs together with the mating arrangement. The starting point is the metal component you need to fit into the assembly: its central opening, formed profile, contact locations and specified material. Share the quantity and any open design questions so the manufacturing scope can be reviewed before quotation.

CUSTOM LIGHTING COMPONENTS · FIT & ASSEMBLYRound Metal Light Housings: Rim Fit, Embossed Panels and Cable EntryHARVLAND provides custom metal stamping and sheet metal fabrication. The round light-housing configuration shown here uses color-coated sheet, with a specified thickness of 0.5 mm and diameter of 265.24 mm. For a custom housing or backplate project, send the part drawing, a sample or photographs together with the mating components so we can review the metal-part requirements and manufacturing scope before quotation.

CUSTOM METAL COMPONENTS · FIT & ASSEMBLYCamera, Fire-Protection & AV Board Brackets for Display ProjectsHARVLAND manufactures custom metal brackets to agreed drawings. The camera, fire-protection and AV board brackets shown here are for different display-related devices, each with its own assembly requirements: the camera interface, the installation area of the perforated part, or the mounting points and clearances around the board. Identify the specific device and installation location, and send a drawing, sketch, sample or installation photograph to discuss manufacturing and quotation requirements.

Materials and purchasing inspectionHow to Read RoHS and REACH Test Reports: Checking Samples, Test Items, ND and Report DatesA supplier sends several PDFs, each showing “Pass” on the cover. What should purchasing check next? First connect each report to the material and surface condition you intend to buy, then review its test scope, result definitions and decision basis. For galvanized sheet, nickel-silver strip or stamped parts, a report is useful only insofar as it answers the specific questions raised by the order.

Materials and purchasing inspectionHow to Inspect Thin-Sheet Hardness: Matching HV, HRB, Test Force and Material ThicknessIf a supplier reports “hardness 200” for a thin sheet but incoming inspection produces another number, do not immediately decide that one party measured incorrectly. The scale, test force, measurement location and specimen preparation determine whether the results can be compared directly. Align these conditions for both steel sheet and nickel-silver strip before deciding whether the material meets the order.

Materials and Incoming InspectionCan Sheet with Scratches, Dents or Pits Be Used? Inspecting Incoming Surfaces and Finished Cosmetic FacesOne sheet has fine lines; another has a shallow dent. The warehouse confirms the grade, production says the parts will be powder coated, and the customer expects a consistent appearance after assembly. Deciding whether the material can be used means linking the mark's location, the sheet's delivery requirements and the face it will become on the part. Establish those relationships before choosing further inspection, sorting, trials or replacement.

Materials and purchasing inspectionHow to Inspect Galvanized Sheet Coating Mass: Both-Side Totals, Distribution and Test MethodsA supplier's report says the coating passes, but an incoming thickness gauge shows different readings on the two faces. Do not immediately conclude that coating is missing, or double the reading from the thicker face. Purchasing, inspection and the supplier first need to agree which face and area the order covers, how sampling works, and what the reported numbers actually measure.

Materials and formabilityHow Rolling Direction Affects Sheet Metal Bending: Checking Bend Lines, Nesting Orientation and CracksWith the same part drawing, changing a blank's orientation on the sheet can change its bending behavior. To understand why, first relate the material's rolling direction to the part's bend line and the tensile direction at the outside of the bend, then check material condition, cut edges and tooling.

Materials and purchasing inspectionIs Hardness Enough for a Spring Contact? Checking Temper, Working Deflection and Force RetentionResistance during assembly does not establish that a spring contact will still press against its mating surface after extended service. Replace “make it springier” with measurable deflection, force and test conditions so that purchasing and engineering can distinguish material condition, part geometry, processing and assembly effects.

Materials and purchasing inspectionHow Steel Sheet Size Affects Part Quotes: Comparing Full Sheets, Slit Coil and Cut-to-Length NestingWith the same steel grade and thickness, a different sheet width or ordered length can change how many parts fit. To understand a quotation, calculate the flat-pattern dimensions, part spacing, purchased sheet count and remaining material together instead of comparing only the price per tonne.

Materials and purchasing inspectionMill Edges, Cut Edges and Part Burrs: What to Confirm Before Buying and Cutting Steel SheetA purchase order for mill-edge sheet does not permit finished parts to be delivered with uncontrolled burrs. A cut-edge delivery description does not mean that holes and outlines cut later have already received their final edge treatment. Separating supply edges, usable sheet area and finished-part edges helps establish what the quotation includes and what to inspect on receipt.

Materials and purchasing inspectionUnderstanding CEV and Pcm: Checking Composition, Formulas and Material Evidence Before WeldingTwo steel inspection certificates report different values: one gives CEV = 0.38, the other Pcm = 0.20. Which material is easier to weld? The numbers cannot be compared directly. First establish the formula behind each value, the material analysis used as input and the requirement against which the result will be assessed. Purchasing and quality personnel can make the subsequent welding review more useful by assembling this information first.

Materials and purchasing inspectionPatterned Steel Plate Thickness: Base Thickness, Pattern Height and Purchasing WeightFor example, a purchase order says “3 mm patterned steel plate”, but a caliper placed on a raised feature reads close to 4.5 mm. That does not establish that the base plate is thicker than ordered, or that the supplier quoted the wrong size. The continuous base and the local raised pattern have different dimensional boundaries. Identify the two surfaces being contacted before comparing the drawing, quotation and delivered material.

Materials and purchasing inspectionReading Steel Quality Designations: B, C, D, E and JR, J0, J2, K2A drawing specifies Q355ND, but the quotation says only “Q355.” Another certificate states “S355, impact passed.” The missing characters may look minor. They can leave the delivery condition, impact-test requirements or evidence for acceptance unresolved.

Materials and purchasingQ355, Q355N and Q355M: How Steel Delivery Condition Changes a Fabrication ReviewSuppose a drawing specifies Q355ND, but the quotation offers Q355MD. The supplier points out that both are in the 355 strength class and have the same thickness. That does not settle the comparison. The different letter relates to how the steel obtains its specified properties, and it matters when deciding whether the planned bending, welding and heating operations remain appropriate.

Materials and incoming inspectionInspecting Incoming Steel Sheet Thickness: Measurement Points, Coatings and TolerancesTwo people measure the same bundle of steel labelled “1.0 mm” and report different numbers. One closes a tool at the edge; the other uses a micrometer farther from it. Before calling the material too thin—or averaging the readings and releasing it—establish what thickness was measured, whether the conditions were comparable and what the purchase requirements actually allow.

Incoming sheet shape and inspectionSteel Sheet from Coil to Cut Length: Inspecting Coil Set, Crossbow and Wavy EdgesA bundle of steel sheets looks orderly under its straps, but one sheet lifts after it is removed. Does that mean the cut-to-length process failed, or did the inspection conditions change? A process description alone cannot settle acceptance. Buyers and processors need to establish what was delivered, where its shape differs, how it was inspected and what the order actually requires.

Incoming material and surface inspectionWhite Rust on Galvanized Sheet: What to Check Before ProcessingA newly opened pack of galvanized sheet has white or gray marks. The warehouse wants to wipe them away, production wants to keep cutting, and purchasing is concerned that the whole delivery may be unusable. Start by recording where the marks are, whether moisture is present, and which material they belong to. Then establish whether the issue affects appearance, the coating, or downstream processing. A photograph alone cannot resolve all three.

Materials and incoming inspectionHow to Read a Steel Mill Test Certificate: Linking Heat Numbers, Chemistry and Mechanical Results to Delivered MaterialPurchasing receives a steel certificate marked 3.1, with numbers in the chemistry and strength fields. Can the material now go to the shop floor? That page alone is not enough. First establish which product and test results it covers, and whether labels and delivery records connect that evidence to the material actually received.

Process and inspectionWhy Does Laser-Cut Sheet Metal Warp? From Incoming Material to Cutting and ReleaseWhen a panel corner lifts after cutting, the shape may have changed during cutting, or the change may only become apparent during cooling, removal of retaining tabs or unloading. If the part looks flat on the machine but not on the inspection table, check whether the two observations used the same support and restraint. Locate the stage where the shape changes before deciding whether to investigate material, cutting paths or measurement.

Material selectionCan Q235, SS400, A36 and S235JR Be Substituted? What to Check Before ApprovalA bracket drawing specifies S235JR, but a supplier quotes Q235B at the same thickness. Another quote says ‘SS400, equivalent to A36’. These materials may all appear in structural-part purchasing, but similar names and partly overlapping strength ranges do not authorize a direct substitution. Acceptance depends on the complete part requirements and evidence for the material actually supplied.

Material selectionHot-Rolled, Pickled and Cold-Rolled Steel: Choosing Material for Brackets and Sheet Metal PanelsSteel sheet destined for bending and painting can have very different priorities in an internal equipment bracket and a visible enclosure. A bracket must transfer loads to its mounting points; a panel also needs the required appearance, flatness and assembly gaps. Start with those requirements when comparing hot-rolled, pickled and cold-rolled sheet, then specify the grade, thickness and surface condition.

Stamping processBridge Lance and Form: How a Raised Metal Bridge Is MadeA bridge lance and form cuts a sheet locally, raises the material between the cuts and retains a connection to the parent sheet at both ends. The raised surface creates an offset from the surrounding sheet. Applications can include local positioning, guides or space for an assembly. To judge manufacturability, review both roots, slit ends, holes on the bridge and the assembly clearance together.

Material selectionChoosing Sheet Metal: SPCC, SECC, SGCC, SPHC, 304, 5052, Q235 and H62An indoor enclosure, an outdoor bracket, a lightweight cover and an electrical contact may all start as sheet metal, but they do not need the same material. Start with the part’s function, load and exposure, then compare the exact grade, supplied condition, thickness, finish and joining method.

Finishing and inspectionHow to Read Salt Spray Test Ratings and Acceptance CriteriaUnderstand salt spray methods, protection and appearance ratings, defect areas and acceptance criteria for metal parts.

Fabrication and inspectionHow to Choose a Metal Deburring Method: Edges, Holes and Internal PassagesCompare deburring methods by burr location, access, quantity and the dimensions and surfaces the part must retain.

Surface finishingCommon Appearance Defects in Electroplated PartsHow peeling, pits, burnt deposits, missing coverage and color variation point to the process steps that need checking.

Metal StampingDense Perforation Distortion and Slightly Convex Tool FacesVentilation panels, metal covers and enclosure panels often contain closely spaced arrays of small holes. Each hole may look simple, and its diameter and pitch may meet the drawing, yet the sheet can bulge or twist after punching, leaving its corners unable to sit flush during assembly. The cause often lies in how the metal remaining around the holes deforms, and how those deformations are released when the sheet leaves the tooling.

Material selectionCopper or Brass? Choose the Material Around the Part’s FunctionCurrent-carrying links, spring contacts and formed covers need different properties. Compare electrical, mechanical and manufacturing requirements before releasing an alloy and temper.

Material selectionChoosing Cold-Rolled Steel Sheet for Covers, Brackets and Formed PartsA cold-rolled label does not tell you how a cover will bend, how a bracket will carry its load or how a painted part will resist corrosion. Connect the sheet specification to the features that decide whether the finished part works.

Material selectionChoosing Galvanized Steel Sheet: Grade, Coating and Finished-Part RequirementsThe zinc coating and the steel beneath it do different jobs. A useful sheet selection identifies both, then checks what cutting, forming, joining and painting leave on the finished part.

Material selectionTinplate for OEM Sheet Parts: Specify the Steel and the SurfaceA tin-coated steel sheet is more than a bright surface. Compare its substrate, temper, coating and finished features before choosing it for a formed cover or electronic component.

Material selectionChoosing Nickel Silver for Formed Contacts and Shielding PartsA silver-colored strip does not identify its alloy or its job. Compare the exact nickel-silver grade and supplied condition against forming, retained contact force, electrical function and the finished surface.

Materials and corrosionGalvanized Steel vs Stainless Steel: Choosing for OEM Enclosures and BracketsCompare two corrosion-protection approaches using the conditions of your actual part. Cut edges, bends, welds and wet joints can change the decision that a comparison of flat sheet prices suggests.

Materials and corrosionWhy Does Stainless Steel Rust? What Rust Marks Tell You to CheckBrown spots on a stainless panel do not all have the same cause. Learn how their location, the exposure history and the surface after cleaning help you decide whether to remove contamination, examine localized damage or review the material and fabrication route.

Surface finishingLiquid Paint Coating: Process Control and Defect DiagnosisThe same black topcoat can look smooth on a large face but sag on a flange. A film without visible holes immediately after spraying may develop pinpoints in the oven. The issue is usually how the coating, substrate, wet-film distribution and film-formation process work together.

Surface finishingAn In-Depth Guide to ElectrocoatingTwo quotations for “black e-coat” may use different resins, pretreatments and cure conditions, with different acceptance rules for cavities, cut edges and fixture contacts. Similar color does not establish equivalent protection on the same enclosure or bracket.

Surface engineeringPVD Coatings for Stainless Steel Parts: Deposition, Color, Wear and Corrosion AcceptancePVD is worth evaluating when stainless steel panels, handles or decorative parts need gold, gunmetal or black finishes. It can preserve metallic texture, produce a particular shade or improve wear under specific contact conditions. A purchase order saying only ‘vacuum titanium coating, scratch resistant, rustproof’ does not define either the process or finished-part acceptance.

Stainless steel enclosure guideWhich Stainless Steel Grade Should You Use for an Enclosure?For most general-purpose sheet metal enclosures, 304 is the usual evaluation starting point. Consider 316 or 316L when chlorides, repeated wet cleaning or persistent moisture increase localized-corrosion risk, and use an L grade when welding makes sensitization control relevant. Other stainless families require a defined reason and fabrication review.
