Irregularly Shaped Steel Stampings With 1-Year Warranty, Mill Test Report Included, Standard Compliant
Product Spotlights
As a leading manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been supplying high-quality irregularly shaped steel stampings since 1998. Our stampings are produced with precision, backed by a 1-year warranty and accompanied by a Mill Test Report (MTR) to ensure full traceability and compliance with industry standards. Whether you need custom profiles for automotive frames, construction brackets, or machinery components, our factory offers reliable solutions that meet your exact specifications.
Our irregularly shaped steel stampings are manufactured using advanced stamping presses and tooling, with strict quality control at every stage. Each batch undergoes rigorous inspection to guarantee dimensional accuracy, material integrity, and surface finish. The included Mill Test Report provides certified chemical and mechanical properties, giving you confidence in the material's performance. We understand that irregular shapes require special attention to tolerances and repeatability, and our experienced team ensures consistent results even for complex geometries.
Key Features & Technical Specifications
- Material Options: Carbon steel (e.g., SPCC, DC01), alloy steel (e.g., 4140, 4340), stainless steel (e.g., 304, 316) – all sourced from reputable mills.
- Custom Shapes: Our tooling department can produce any irregular contour, including notched, curved, tapered, or asymmetrical designs, based on your CAD drawings or samples.
- Thickness Range: From 0.5 mm up to 20 mm, with tolerances as tight as ±0.05 mm (depending on the material and thickness).
- Size Capability: Maximum blank size up to 1500 mm × 800 mm, suitable for medium to large stampings.
- Secondary Operations: We offer deburring, tapping, countersinking, welding, and assembly services to deliver finished parts.
- Surface Treatments: Available options include galvanizing, powder coating, zinc plating, black oxide, oiling, and passivation, providing corrosion resistance and aesthetic appeal.
- Quality Assurance: 100% dimensional inspection using CMM, go/no-go gauges, and visual checks. Each shipment includes a Mill Test Report and a certificate of conformance.
- Standard Compliance: Our stampings meet common industry standards such as ASTM A36, DIN 1623, JIS G3141, or equivalent – we can tailor to your required standard.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for irregularly shaped steel stampings?
A: Our standard MOQ is 500 pieces for mild steel stampings. For stainless steel or complex shapes, the MOQ may start at 300 pieces. Lower quantities are available for sampling or prototyping. -
Q: Can you work from a sample or drawing?
A: Yes. We accept both 2D/3D CAD files (e.g., STEP, IGES, DXF) and physical samples. Our team can reverse-engineer the sample to create production tooling. -
Q: How do you ensure the quality of irregular stampings?
A: We use a combination of first-article inspection (FAI), in-process gauging, and final dimensional checks. Our quality system includes statistical process control (SPC) for critical dimensions. The Mill Test Report verifies material properties. -
Q: What standard does “standard compliant” refer to?
A: “Standard compliant” means that our stampings meet typical industry standards such as ASTM, DIN, JIS, or GB. We can also produce to your specific standard if you provide the requirements. Without a specific standard named, we default to our internal quality standards which are comparable to international norms. -
Q: Is the 1-year warranty applicable to all parts?
A: Yes, the warranty covers manufacturing defects and material defects for one year from the date of shipment. It does not cover damage caused by misuse or improper installation. -
Q: Do you offer any surface treatment or finishing?
A: Absolutely. We can provide galvanizing, powder coating, zinc plating, black oxide, oiling, and other finishes. Please specify your requirements when inquiring. -
Q: How long does it take to produce a new tooling for irregular stampings?
A: Tooling fabrication typically takes 10–15 working days, depending on complexity. Once the tool is ready, production lead time is 15–20 working days. -
Q: Can you ship to different ports besides Tianjin and Qingdao?
A: Yes, we commonly ship from Tianjin, Qingdao, Shanghai, and Foshan. We can also arrange door-to-door delivery via freight forwarders based on your preference.
Trusted by global buyers from North America, Europe, Southeast Asia, Africa, and Oceania, our factory has maintained an annual export value of US$5–10 million, a testament to our reliability and product quality.
