Steel structure buildings feature high fire resistance and strong corrosion resistance. The main bearing components are composed of steel, including steel columns, steel beams, steel structures, and steel roof trusses. Each component is connected using welds, bolts, or rivets.

The roof and wall can be made of composite panel or veneer. Galvanized sheet metal prevents rust and corrosion. Self-tapping screws make the connection between plates more secure, preventing leakage. Composite panels with PU, EPS, fiberglass, or rock wool cores provide excellent thermal insulation, heat insulation, and fire-retardant properties. Brick walls can also be used for steel structure maintenance.

Applications include large-scale workshops, warehouses, supermarkets, entertainment centers, and modular steel structure garages.

Qingdao Ruly Steel Engineering Co., Ltd is a professional steel structure fabrication and engineering company, located in Qingdao, China, which integrates steel structure design, research and development, manufacturing and installation. The project types include prefabricated steel workshop, warehouse, logistics park and other light steel structure of the civil building system, high-rise residential buildings, exhibition center, stadium, airport station and bridge, Power plant, chemical plant, oil and gas, mining, etc.

Our company's steel structure processing plant now covers an area of 35,000 square meters, plant 20,000 square meters with more than 100 employees. The monthly production capacity for steel structure is more than 1500 Tons. Our steel structure components include light/heavy H steel, BOX steel, Cross shaped section steel, large diameter submerged arc straight-weld pipe, steel model structure, C/Z purlin and machining fitting components.

We have three subordinate steel structure companies, which have passed and strictly implemented ISO9001:2008 quality management system, ISO14001:2004 environmental system, GB/T28001:2001 occupational health system, and obtained ASTM certification in the United States, and international SGS product certification. We have obtained the right of export, design, installation and consultation from the ministry of foreign trade and economic cooperation.

Our entrepreneurial concept is "Quality first, Technology ahead, Innovation continually". We build strong relationships of trust with our clients, truly understanding their needs and bringing them the most reasonable solutions.
