Beams and Columns: Structural members fabricated from standard solid timber and marine structural materials, designed to withstand light to moderate static and dynamic loads.
Support Frames: Structural frame assemblies dedicated to supporting and securing equipment, piping systems, construction materials and other auxiliary facilities.
Crane Rails: Specialized rail systems for the operational use of light and medium-duty mobile travelling cranes.
Bridge Supports: Tie rods and bracing members applied to the structural reinforcement of small-span bridges.
Custom Industrial Packaging
Secure Packing Solution: Heavy-duty steel bands paired with corner guards to stop flange distortion during transit.
Anti-corrosion Treatment: All finished goods are entirely covered with waterproof plastic film or woven sacks, plus built-in desiccant packs to draw away dampness.
Full Item Traceability: Every single bundle comes fitted with weather-resistant metal labels clearly stamped with heat batch numbers, material grades (Gr.50) and dimensional specs.
Streamlined Shipment Arrangements
Container Loading Options:
20GP containers: Ideal for goods measuring 5.8 meters long.
40HC containers: Best matched with 11.8m or 12m lengths; strongly advised for large-scale construction projects.
Flexible Loading Alternatives: Open-top containers enable convenient crane lifting, while breakbulk shipment works well for large tonnage orders.
Localized Delivery & Logistics
Direct Site Delivery: Our branch offices in the US and Guatemala arrange flatbed truck transport straight to your job site.
Structural Protection Guarantee: Timber dunnage blocks are placed between stacked bundles to avoid bending issues throughout stacking and transit.
Q1: What are the uses of ASTM A572 steel channels?
They are also used in the manufacture of machinery, heavy equipment, and automobiles.
Q2: What grade of A572 steel channel is it?
Due to its high strength and excellent structural performance, ASTM A572 grade 50 is the best-selling grade.
Q3: What is the difference between A572 and A36?
Because A572 grade 50 has a higher yield strength than A36, it is more suitable for construction requiring heavier structural components.
Q4: Do you offer OEM services?
Yes, we can provide customized processing services based on your project requirements and drawings, such as cutting, drilling, welding, and surface treatment.
Q5: What types of surface treatments do you offer?
We offer surface treatments such as black plating, oiling, painting, and hot-dip galvanizing to meet different corrosion protection requirements.
