STEEL STRUCTURE DESIGN
Royal Group’s engineering team develops tailored steel structure designs for warehouses, production halls, commercial buildings, airports and infrastructure works. We utilize professional 3D modeling software and a complete set of construction drawings to save materials, enhance on-site assembly efficiency, and control the total project investment.

STEEL STRUCTURE PROCESSING
Equipment: CNC plasma cutting machine, CNC spark cutting machine, hydraulic cutting machine
According to the project drawings, the steel plates and steel sections are precisely cut. For the production of thick plates for steel structures, plasma and flame cutting may be employed, while small profiles are cut using hydraulic shears to ensure the accuracy of the shape and size of the steel structure.
Equipment: CNC bending machine, cold bending bending machine, forming machine
The steel is processed into various components, such as roof beams, roof pipes, edge seals, arc-shaped beams, and circular arch structural components, ensuring high-precision dimensions and perfect consistency of the products.
Equipment: submerged arc welding machine, manual arc welding machine, carbon dioxide shielded welding machine
All H-shaped steel, columns, support structures, and connection components are manufactured using proven welding techniques. All weld seams comply with international quality standards to ensure structural strength and stability.
Equipment: CNC drilling machine, hydraulic press
The bolt holes and connection holes are precisely machined to ensure good assembly compatibility and ease of on-site installation.
Equipment: grinding machine, sandblasting equipment, hot-dip galvanizing system
The steel surface is cleaned of oxides, residues, and contaminants. Options include spraying or hot-dip galvanizing treatment, suitable for various indoor and outdoor environments, providing long-term corrosion prevention.
Equipment: installation platform, laser measuring instrument, positioning device
Pre-installation and size verification are conducted before shipment to ensure alignment accuracy and welding compatibility, meeting project technical requirements.
STEEL STRUCTURE TESTING
To ensure outstanding performance, corrosion protection and long service life, all steel structures, pipes, sheet materials and steel construction products are comprehensively inspected for quality in accordance with international standards.
1. Salt Spray Test
Standard: ASTM B117 / ISO 11997-1, Part 1
This test is used to evaluate the corrosion resistance of galvanized and coated steel products, ensuring the stable use of the products in coastal, marine and humid environments.
2. Adhesion Test
Standard: ASTM D3359 / ASTM D4541 / ISO 2409 / ISO 4624
The wet adhesion test is used to examine the adhesion between the coating and the metal surface to prevent blistering, damage and premature detachment of the coating.
3. High Temperature and High Humidity Resistance Test
Standard: ASTM D2247 (40°C / 95% relative humidity) / ASTM D2247
The high temperature and high humidity test is conducted in a humid environment to verify the stability of the coating and ensure good moisture resistance and extend the product's service life.
4. Ultraviolet Weather Resistance Test
Standard: Compliant with ASTM G154 Specification
This test simulates long-term exposure to ultraviolet environment to evaluate the fading, degradation and aging resistance of the coating.
5. Coating Thickness Measurement
Standard: ASTM D7091 (film thickness) / ASTM D1212 (wet film thickness)
Ensure that the coating thickness meets the design requirements, effectively preventing corrosion and guaranteeing the stability of the product.
6. Crack Resistance Test
Standard: ASTM D2794
This test is used to detect the hardness of the coating and evaluate its ability to prevent cracking and damage during transportation, product use and on-site installation.
SURFACE TREATMENT
PACKAGING AND SHIPPING
If necessary, I will wrap the steel structural components with complete protective films to prevent dust and moisture, and to avoid damage during transportation. In the office workshop, the parts are safely lifted and delivered using cranes or frame-type cranes installed on vehicles. After the parts are neatly placed and fixed, they are properly loaded into containers. The entire loading and container loading process is strictly monitored. The products are properly arranged to ensure that the metal components remain intact during the long sea transportation and arrive at the project site on time.
