Yes, we encourage potential clients to evaluate our craftsmanship and material quality through physical samples. Please contact our sales team to discuss sample policies, including costs and shipping arrangements.

Customization is one of our core strengths. We can develop products according to your drawings, specifications (such as ASTM, DIN, ISO, GB), or specific application requirements, with options for material selection (stainless steel or carbon steel), dimensions, strength grades, and surface treatments (e.g., galvanizing, Dacromet, passivation).

We implement strict quality control throughout the entire process, from raw material inspection to finished product delivery. For stainless steel and carbon steel materials, we conduct composition and mechanical property tests. Advanced testing equipment (e.g., hardness testers, tensile testing machines) is used during production to ensure every batch meets standards and customer expectations.

MOQ varies depending on the product type, material, and specifications. Standard products have a defined MOQ, while custom orders offer more flexibility. We will provide the most cost-effective solution based on your needs.
