Our Partners
All products comply with global mainstream standards: API 5L/5CT, ASTM A106/A53/A335, EN 10216, ISO 3183, JIS and GB standards.
Carbon Steel
ASTM A572/S355JR is a low-alloy high-strength structural carbon steel coil, available in grades 42, 50, 60, and 65. It features light weight, high strength, good toughness, and excellent machinability, making it an ideal material for structural applications.
Galvanized Color Coating
Pre-painted Galvanized Steel (PPGI) is a pre-coated steel plate made from hot-dip galvanized steel (GI), electro-galvanized steel (EG), etc. as the base material. After surface treatment processes such as degreasing, cleaning, and chemical pretreatment.
Stainless Steel
304 austenitic stainless steel coil contains 18% chromium and 8% nickel. It has good corrosion resistance, is easy to process and weld, and is a general-purpose stainless steel used in kitchenware, chemical industry, and decoration.
Steel Profiles
It possesses excellent corrosion resistance, oxidation resistance, and flexural strength, making it suitable for load-bearing structures in corrosive environments.
Steel Wire
It has a smooth, silvery-white surface, good plasticity and toughness, is easy to bend, bundle and weld, has high dimensional accuracy, and is free of oxide scale.
Alloy
GB/T11251 1345 is a national standard hot-rolled alloy structural steel coil, belonging to medium carbon manganese steel. It has high strength, high wear resistance, high hardenability, moderate cold deformation plasticity, good machinability, and little decrease in toughness after heat treatment.
API Spec 5L
X42 grade microalloyed pipeline steel has a yield strength of ≥290 MPa. It improves the strength of grade B by adding Mn and microalloying. It has excellent weldability and is the main steel grade for medium and low pressure pipelines. It is available in both coiled and medium-thick plate forms.
Pressure Vessel
ASTM A202 series pressure vessel steel plates are divided into two grades, A and B. They are carbon manganese silicon steel plates specifically designed for the welding and manufacturing of boilers and pressure vessels. The maximum thickness is limited to 50 mm (2 inches).
