Capabilities
Every process of Sutai products has been strictly inspected, from the
mechanical properties (tensile, yield, elongation) and chemical composition of raw materials (C, Si, Mn,
P, S, Cu, N...) to inspections in the production process, including dimension inspection, weld
penetration test, cross-cut test of powder spraying for surface treatment, zinc coating and relevant
salt spray test of galvanized parts. Sutai does well in every detail to ensure product quality.
