Frequently Asked Questions
Q1: What is the difference between SS400 and other grades like Q235 or A36?
A: SS400 is a Japanese standard grade with tensile strength of 400–510 MPa, similar to Q235 in China (GB/T) and A36 in ASTM. However, each standard has slight differences in chemical composition and mechanical properties. Our SS400 H-beam complies strictly with JIS G3101, ensuring compatibility with projects designed under Japanese standards.
Q2: Do you provide Mill Test Reports for each shipment?
A: Yes, we include a Mill Test Report (MTR) for every batch of H-beams. The MTR contains the chemical analysis and mechanical test results, traceable to the heat number.
Q3: What sizes and lengths are available?
A: We offer a wide range of sizes from 100×100 mm to 900×300 mm. Standard lengths are 6m and 12m, but we can produce custom lengths according to your requirements. Please contact us with your specific dimensions.
Q4: Can you provide surface treatment like painting or galvanizing?
A: Yes, we offer options such as black finish, painted (primed or finished), and hot-dip galvanizing. Let us know your surface protection needs.
Q5: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 25 metric tons per size, but we can be flexible for trial orders or special projects. Please inquire for details.
Q6: How do you ensure the quality of the products?
A: We have an ISO9001 quality management system in place. We perform incoming material inspection, in-process checks, and final dimensional/mechanical testing. Each beam is inspected before packaging and shipping.
Q7: What is the delivery time?
A: For standard sizes, delivery is usually 15–20 days after receipt of deposit. For custom sizes, please allow 25–30 days. We always strive to meet your project schedule.
