Pre-engineered Bolt Steel Structure Garage Workshop Warehouse Building With Sandwich Panel And Galvanized Steel Frame

Steel structure warehouses are modern storage buildings constructed using high-strength steel as the core material and combining standardized factory prefabrication with rapid on-site assembly processes. They are suitable for storage needs in various fields such as industry, logistics, e-commerce, and agriculture, and have multiple advantages such as high efficiency, safety, flexibility, and environmental protection.

Breaking the limitations of traditional brick-concrete and concrete warehouses, they have become the mainstream preferred solution for modern warehouse construction. They can meet the storage needs of conventional goods and are also suitable for complex storage scenarios such as heavy equipment, high-bay racking, and automated sorting, achieving a dual improvement in storage space utilization and operational efficiency.

The core components utilize high-strength H-beams, channel steel, and I-beams. Depending on the warehouse scale and span requirements, three mainstream structural types can be selected:

• Standardized Portal Steel Frames: Economical and efficient, standard spans of 20*30 meters and 30*40 meters, saving 30% on steel consumption and reducing construction costs by 40%, suitable for small to medium-sized conventional warehouse scenarios
• Large-span Space Trusses: Enables column-free single-span spaces from 40*60 meters to 140 meters, with industrial-grade load-bearing capacity, suitable for large logistics hubs and heavy cargo storage scenarios
• Multi-layer Prefabricated Steel Structures: BIM-driven modular design, increasing vertical space utilization by 300%, suitable for land-scarce urban center warehouses and intelligent automated warehouse scenarios

The roof utilizes color steel plates and sandwich panels (rock wool, polyurethane), providing rainproof, windproof, heat insulation, and thermal insulation functions. Flat, pitched, or arched roofs can be selected according to needs, optimizing drainage.

The walls use color steel sandwich panels, offering flexible options for insulation, fireproofing, and corrosion resistance, adapting to the temperature, humidity, and protection requirements of special storage scenarios such as cold chain, and hazardous chemicals. Skylights can be pre-installed to improve natural light utilization and reduce lighting energy consumption.

The foundation is designed based on geological conditions, using independent or strip foundations, simplifying construction and controlling costs. Supporting facilities can be customized as needed, including:

• Roller shutters and sliding doors for easy access of large vehicles
• Ventilation systems
• Fire protection systems (sprinklers, smoke detectors, fire extinguishers)
• Lighting systems
• Grounding and lightning protection systems
• Interfaces for automated warehousing equipment (stacking cranes, intelligent sorting lines)

These systems help enterprises achieve intelligent warehousing upgrades and adapt to unmanned operation requirements.
