APPLICATION
Steel Structure Warehouse
The steel structure warehouse of Royal Steel Group is suitable for logistics hubs and warehousing projects. It features a column-free large-span design, a short construction period, and helps customers control costs and enhance operational profits.
Steel Structure Workshop
Ideal for production and processing zones. It features an open inner space for easy equipment layout, and allows flexible modification and expansion later on.
Steel Structure Industrial Plant
Steel structure buildings can be used as production plants, power stations and other heavy-load industrial supporting buildings. Steel structures hold up well in demanding industrial settings with great load capacity and robust, stable construction.
Steel structure commercial buildings
Steel structures can be used for shopping malls, office buildings, exhibition halls and shops. Because steel structures are in line with modern architectural styles and have high space utilization rates.

STEEL STRUCTURE PROCESSING
Cutting Process
We use CNC plasma cutting machines, CNC flame cutting machines, and hydraulic shearing machines to cut steel plates and profiles according to the drawings. Thick plates are cut using plasma or flame, while thin plates are sheared using hydraulic shears. The cuts are smooth and the dimensions are accurate.
Forming and Bending Process
Equipped with CNC bending machines and roll forming machines, we can produce roof trusses, gutters, edges, arc-shaped beams, and round pipes, etc. The formed dimensions are stable with small errors.
Welding Process
We use submerged arc welding, manual arc welding, and carbon dioxide gas shielded welding equipment to process H-beams, steel columns, trusses, and connection accessories. All weld seams are welded according to international standards to ensure the structure is strong and durable.
Drilling and Punching Process
Processed by CNC drilling machines and hydraulic punching machines, we can drill bolt holes and connection holes. The hole positions are highly accurate, making it convenient to install and connect on-site.
Surface Treatment Process
Equipped with shot blasting machines, sandblasting equipment, and hot-dip galvanizing production lines, we clean the surface of the steel to remove rust and oxide scales. We can do painting or hot-dip galvanizing. It can be used both indoors and outdoors, with a long-lasting rust prevention effect.
Pre-assembly Process
Using assembly platforms, laser measurement tools, and positioning fixtures, we conduct trial assembly and size checks before shipment to ensure that the assembly is complete and meets the project requirements.
STEEL STRUCTURE TESTING
In order to achieve excellent performance, rust prevention, and long service life, all the steel structures, steel pipes, steel coils, and structural steel products are subjected to the whole process of quality testing based on the international standards.
1. Salt Spray Test
Standards: ASTM B117 / ISO 11997-1, Part 1
Test the corrosion resistance of galvanized and coated steel, making sure of good performance in seashore, marine, and high-humidity environments.
2. Test of coat adhesion
Standards: ASTM D3359 / ASTM D4541 / ISO 2409 / ISO 4624
During the wet adhesion test, the coating's adhesion to the steel substrate is evaluated to avoid delamination, flaking, and early coating breakdown.
3. Humidity Resistance Test
Standard: ASTM D2247 (40°C / 95% RH) / (ASTM D2247)
Test HTHH (Coating Stability In High Temperature And Humid Climate) - Used to check the stability of coating in high temperature and humidity to achieve good moisture proofing and long life.
4. UV Weathering Test
Standard: ASTM G154 - Equivalent
It emulates prolonged UV exposure to assess color, chalk, and weather-related deterioration resistance.
5. Coating Thickness Inspection
Standards:: ASTM D7091 (DFT) / ASTM D1212 (WFT)
Ensure the thickness of the coating layer complies with your project requirements for best corrosion protection and product stability.
6. Impact Resistance Test
Standard: ASTM D2794
Quantifies the toughness of a coating to resist chipping, cracking, and other damage during shipping, handling, or field application.
SURFACE TREATMENT
PACKAGING AND SHIPPING
1. All our steel structure components are protected by applying protective film wrapping measures as necessary to prevent them from being bumped or getting damp during transportation.
2. During loading onto the vehicle, the steel structure will strictly follow safety lifting procedures. Professional equipment such as vehicle-mounted cranes and forklifts will be used to work together to prevent any damage to the steel structure.
3. Inside containers, goods are neatly arranged and firmly fastened to stop movement and shifting.
4. The entire process is carried out in a standardized manner to ensure the integrity of the goods and their safe delivery to the designated port of the customer.
WHY CHOOSE OUR STEEL STRUCTURES?
A suitable partner is crucial for the safety, cost and lifespan of a project. We leverage our professional technology, high-quality materials and comprehensive service to create durable steel structures.
