Our factory's core export advantages for American standard angle steel:

Complete specifications, one-stop sourcing: We maintain a full stock of mainstream specifications of American standard equal/unequal angle steel, which can be shipped in conjunction with American standard H-beams, channel steel, and steel plates, saving customers comprehensive costs in procurement, communication, and sea freight.

Strictly adhering to ASTM A36/A572 Gr50/A992 standards, chemical composition and mechanical properties meet standards, supporting international third-party testing, ensuring zero risk in customs clearance and acceptance.

High-precision rolling, superior quality: Produced with dedicated American standard shaping rolls, dimensions, angles, straightness, and torsion conform to ASTM A6 tolerance standards; surface free of cracks, folds, and oxidation defects, suitable for welding, galvanizing, and deep coating processing.

Large-scale hot-rolling automated production line, fast delivery of in-stock items, efficient production scheduling for customized and deep-processing orders; optimized container loading solutions, increasing container capacity and reducing sea freight costs.

No middlemen's markup, factory base price supply;

Comprehensive customization service: arbitrary measurement, cutting, drilling, beveling, sandblasting, anti-corrosion painting, hot-dip galvanizing integrated processing

Support for third-party re-inspection, in line with the engineering acceptance standards of various countries

Payment Methods

Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
