Our standard MOQ is 1 ton for stock sizes, but we can accommodate smaller quantities for sample orders. For custom lengths, please consult our sales team. -
Can you provide custom lengths?
Yes, we can cut beams to any length between 1m and 12m, with a tolerance of ±5mm. Longer lengths up to 18m are available for sea freight. -
What surface treatment options are available?
Standard is black (as rolled) with mill scale. We also offer shot blasting, red oxide primer painting, or hot-dip galvanizing (upon request with additional cost). -
Do you have third-party inspection certificates?
Yes, we can provide Mill Test Certificates (MTC) conforming to EN 10204 type 3.1. Additionally, we can arrange SGS, BV, or other third-party inspection at the buyer's cost. -
What is the delivery time?
For stock sizes, delivery is within 7-15 days after order confirmation. For customized orders, it may take 20-30 days depending on the volume. -
How do you pack the beams for export?
