High strength differences between a573 grade 70 and a588 grade K steel for bridge

Our company was founded in 2000, which initially committed to providing high-quality steel differences between a573 grade 70 and a588 grade K steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export differences between a573 grade 70 and a588 grade K steel steel to the international market, opening up the international steel market.

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.

Laser cutting differences between a573 grade 70 and a588 grade K steel has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the differences between a573 grade 70 and a588 grade K steel cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
