Our optional raw materials include ordinary carbon steel, galvanized steel sheet, zinc-aluminum-magnesium plate, color coated steel plate, cold rolled steel plate and other high-strength anti-corrosion steel. We will recommend the most suitable material according to different working conditions such as outdoor exposure, humid environment and heavy load bearing. In terms of quality control: We will check official material certificates of all incoming raw materials to reject unqualified raw materials; key processes like rolling, bending and punching are controlled strictly to limit dimensional tolerance within the standard range; finished products will be sampled comprehensively to check straightness, wall thickness and surface condition. All production procedures are finished in our own workshop without outsourcing processing, so we can control quality from the source. We will take reasonable solutions for quality problems caused by our production mistakes.

Yes, we provide free professional technical support for all cooperative customers. Before production, our engineers can optimize structural design to improve installation convenience and structural stability. After delivery, we can provide simple installation sketches, parameter reference and operational precautions online. If you encounter difficulties during on-site installation, you can send on-site pictures or videos to us, our technical engineers will guide you to solve problems remotely. For large engineering projects, we can discuss the possibility of arranging professional technical personnel to the site for guidance according to actual cooperation situation.
