FAQ
Q1: What is the difference between S355J2H and S355JR square tube?
The core difference lies in low-temperature toughness. S355JR only supports room-temperature impact test, while S355J2H passes -20℃ low-temperature impact test, with better brittle fracture resistance. It is more suitable for cold regions, dynamic load structures and high-safety-level projects.
Q2: Can you provide customized sizes and fixed-length cutting?
Yes. We support custom wall thickness, square size and fixed-length cutting according to customer drawings and requirements. Non-standard sizes and special processing services (drilling, bending, galvanizing) are all available.
Q3: What quality certificates can you provide?
We can provide official Mill Test Certificate (MTC), CE certificate, ISO 9001 quality system certificate, certificate of origin and other documents to meet global engineering bidding and customs clearance requirements.
Q4: Is S355J2H square tube suitable for outdoor and humid environments?
The original black finish tube has basic rust resistance. For long-term outdoor and humid environment use, we recommend hot-dip galvanizing or anti-corrosion painting treatment to greatly extend service life and enhance corrosion resistance.
Q5: What is your minimum order quantity (MOQ)?
Standard sizes support small batch trial orders (1 bundle). Customized sizes have flexible MOQ based on specifications. We support both bulk wholesale and retail orders to meet different customer needs.
Q6: How to ensure product quality consistency?
All products are produced in strict accordance with EN 10210 standards. We conduct full inspection on dimension, mechanical properties and chemical composition before delivery, with batch sampling test to ensure stable and consistent product quality.
