Sheet Metal Fabrication Quote Online

We support common sheet metal fabrication quotation file formats:

• 2D: DWG / DXF / PDF (fully dimensioned engineering drawings recommended)
• 3D: STEP / STP, IGES / IGS (for assembly, interference, and flat-pattern review)
• Compressed package: ZIP / RAR (multiple parts/multiple versions can be packaged and uploaded)

Provide a 2D engineering drawing with material thickness, tolerances, and bending or welding requirements for the most accurate quote and DFM review.

Yes. You can start with any of the following:

• Provide samples/photos/dimension sketches: we can help collate key dimensions and evaluate workmanship
• Provide reference links/usage scenarios: engineers can give structural suggestions and feasible solutions
• For assemblies with incomplete drawings, identify critical surfaces and hole-position datums.

For assembly-critical or production parts, provide a PDF, DXF, or DWG engineering drawing for final review.

We support one-off parts, low-volume runs, and volume production.

• One-off and low-volume parts: design validation, fit checks, functional prototypes, and rapid iteration
• Batch: Stable delivery of chassis cabinets, shell panels, bracket structural parts, etc.

For an evolving design, use a low-volume pilot run to confirm dimensions and assembly fit before full production.

The accuracy and tolerance of sheet metal parts depend on the material, plate thickness, structural complexity and bending/welding process. Common references:

• Cutting/Punching: Typical ±0.1–0.2 mm
• Bend dimensions: Typical ±0.2–0.5 mm (depends on bend radius, springback, datum)
• Welded assemblies: controlled from assembly datums; critical dimensions are reviewed individually

If there are critical assembly hole spacing, positioning datum or assembly clearance requirements, please clearly mark the tolerance and datum on the drawing, and we will confirm it separately during the DFM stage.

Common sheet metal materials include:

• Cold rolled steel / galvanized sheet
• Stainless steel (such as 304/316, etc.)
• Aluminum alloy (such as 5052, etc.)

Common plate thickness range (evaluated by project):

• 0.5–6.0 mm (Thinner/thicker can be evaluated separately for process and cost)

Optional surface treatment (adapted according to material):

• Powder coating or paint, screen printing, and laser marking
• Electroplating, brushing/polishing (stainless steel)
• Anodizing (aluminum parts, evaluated based on structural and appearance requirements)

Include the application and applicable standards when color, corrosion resistance, wear resistance, or cosmetic grade is critical.

Lead time depends on complexity, quantity, welding, and finishing. Typical ranges are:

• Cutting + Bending: 3–7 business days
• Including welding assembly: 5–10 business days
• Including surface treatment such as spraying/electroplating: add 2–5 business days on top of the above (depending on the process)

If you have a firm trial-assembly, delivery, or exhibition deadline, include the required date and priority so we can review expedited scheduling.

Yes. We complete a sheet metal DFM review before production, covering:

• Plate thickness/material and process matching
• Minimum hole diameter, hole margin, notch and flange feasibility
• Bending radius, springback, interference and unfolding risks
• Welding positions, assembly standards and deformation risks

All modification suggestions will be confirmed with you first, and the design will not be changed without confirmation.

If critical information is found to be missing or a process risk exists, we will:

• Point out missing items: plate thickness/material, bending angle, hole position reference, tolerance, surface requirements, etc.
• Explain risk points: bending interference, hole edge cracking, welding deformation, assembly errors, etc.
• Provide feasible solutions: suggestions for supplementary standards, structural optimization or alternative process paths

The goal is to improve manufacturability and delivery consistency without changing core design intent.

Yes. First-article approval and assembly-fit checks are available for low-volume and multi-part projects:

• First article confirmation: Prioritize key hole spacing, assembly benchmarks and appearance requirements
• Assembly-fit check: confirm how multi-part enclosures, brackets, and welded components fit together

If you need first article confirmation, please indicate "first article confirmation" and key size points in the order/remarks.

Get started in three steps:

• Upload engineering drawings (DXF/DWG/PDF recommended, attach STEP if necessary)
• Supplementary requirements: material/plate thickness, quantity, surface treatment, critical tolerances and expected delivery time
• Approve the quote and DFM feedback, then proceed to production and delivery

For faster review, also provide bending instructions, welding requirements, finish standards, and assembly datums.
