STEEL STRUCTURE PROCESSING
Equipment includes CNC plasma cutters, CNC flame cutters and hydraulic shears.
All steel plates and profiles are cut precisely following project drawings. Plasma and flame cutting handle thick materials, while hydraulic shearing works for thin steel pieces to deliver clean edges and precise dimensions.
We use CNC press brakes, cold bending equipment and rolling machines.
Steel parts can be shaped into purlins, gutters, flashing trims, curved beams and round sections. Every finished part maintains high dimensional accuracy and stable quality.
Our welding shop applies submerged arc welding, manual arc welding and CO₂ gas shielded welding technologies.
Our advanced welding methods create H-beams, steel columns, trusses and connection elements. Each weld follows worldwide quality standards for dependable structural performance.
We are equipped with CNC drilling machines and hydraulic punchers.
Bolt holes and connecting cutouts are machined precisely, ensuring good fitting and simple on-site installation.
We have shot blasting machines, sand blasting tools and a hot dip galvanizing line.
Steel surface rust, mill scale and contaminants are completely cleaned away. Customers may select paint coating or hot dip galvanizing for indoor and outdoor applications to obtain durable corrosion resistance.
Assembly platforms, laser measuring instruments and positioning jigs are available.
Pre-assembly and dimension checks are completed before delivery. We verify fitting accuracy, welding performance and full compliance with project requirements.
STEEL STRUCTURE TESTING
To achieve outstanding performance, dependable corrosion resistance and longer service life, all steel structures, steel pipes, steel coils and structural steel products undergo complete quality checks in accordance with international standards.
1. Salt Spray Test Standards:
ASTM B117 / ISO 11997 1 Part 1 This assessment measures the corrosion resistance of galvanized and coated steel. It confirms steady performance under coastal, marine and high humidity operating environments.
2. Coating Adhesion Test Standards:
ASTM D3359 / ASTM D4541 / ISO 2409 / ISO 4624 Wet adhesion evaluation tests the bonding strength between coating and steel substrate. It avoids peeling, layer separation and early coating damage.
3. Humidity Resistance Test Standard:
ASTM D2247 (40°C / 95% RH) Also called the HTHH test for coating stability in hot and humid conditions. It verifies coating performance under high temperature and humidity to keep excellent moisture resistance and extend service life.
4. UV Weathering Test Standard:
ASTM G154 or equivalent This test replicates prolonged UV radiation. It evaluates resistance to color loss, chalking and outdoor weather aging.
5. Coating Thickness Inspection Standards:
ASTM D7091 (DFT) / ASTM D1212 (WFT) We confirm coating thickness meets your project requirements to maximize anti-corrosion capability and stable product quality.
6. Impact Resistance Test Standard:
ASTM D2794 It quantifies coating toughness to stop chipping, cracking and mechanical harm during shipment, handling and field erection.
SURFACE TREATMENT
PACKAGING AND SHIPPING
Packaging
All the steel structure components we deliver will be equipped with corresponding protective measures to prevent structural deformation or surface damage caused by improper protection during transportation. Moreover, in some key parts of special components, cushion pads and protective corners will be added to ensure that the steel structure components can be firmly and reliably fixed.
Transportation
Finished components can be selected for appropriate transportation methods based on size, weight and delivery requirements, including truck transportation, container transportation, etc. During loading, the positions of the components will be arranged reasonably, and lifting equipment will be used for assistance in loading and unloading. Reinforcement measures will be taken to prevent sliding, collision and damage during transportation. The steel structure products will be safely delivered to the project site or designated warehouses.
WHY CHOOSE OUR STEEL STRUCTURES?
A suitable steel structure partner directly affects the safety, cost and lifespan of the project. Relying on professional engineering capabilities, high-quality materials and one-stop services, we provide durable and reliable steel structures.
1. High-quality materials, stable structure
We source high tensile steel meeting ASTM, EN, JIS and GB specifications. Heavy load H-beams and steel trusses feature outstanding load capacity, great seismic performance and long term durability.
2. Professional customization, precise design
Using BIM and Tekla software for digital design, the components have high precision and can control large-span deformation, reducing human errors before processing.
