What can we ensure?

Steel grades and specifications

We provide mainstream structural steel grades such as Q235 and Q345, covering various grades of major domestic and foreign standard systems such as GB, JIS, DIN, ASTM, etc., which can meet different strength and toughness requirements.

technical standard

We produce steel plates in strict accordance with industry standards and customer special needs to ensure that the chemical composition and mechanical properties of the steel plates 100% meet the corresponding technical requirements. And provide third-party testing reports.

Supply/delivery/payment

1. Delivery Time:30-50 days, 7 days for stock goods.

2. Loading Port:Shanghai ,Tianjin, Qingdao.
3. MOQ:1 Pcs.

4. Payment method and term: wire transfer and letter of credit

Surface Quality

The surface quality of our steel plates reaches the roughness requirement of 9000, and the rolling process is strictly controlled to ensure that there are no defects on the surface, which meets the needs of the building structure and engineering machinery industries.

size control

We use CNC cutting and advanced online measurement control systems to ensure that the dimensional accuracy of steel plates reaches tolerance level M and provide corresponding dimensional inspection reports.

Packaging and protection

We use wooden pallet packaging or anti-corrosion and dust-proof film packaging, and specially process the edges of the boards to effectively prevent surface damage during transportation and storage.
