We directly supply steel structure mezzanine floor racks, an efficient space expansion solution designed specifically for warehouses with sufficient height. Its core advantage is to expand the single-layer warehouse space into two or three layers, maximizing the use of vertical space, greatly increasing the storage capacity, and solving storage problems without expanding the workshop, with outstanding cost performance. The product is made of high-quality steel, and the main structure is composed of uprights, main beams, secondary beams and floor slabs. It has a stable structure and strong load-bearing capacity. The conventional load-bearing capacity can reach 300-1500kg/㎡, and the heavy-duty specification can be customized to 8 tons/㎡, suitable for the storage needs of various industries such as hardware, machinery, e-commerce and logistics. Adopting a fully assembled design without on-site welding, it is easy to install and disassemble. The layout and number of layers can be flexibly customized according to the actual size, height and goods specifications of the warehouse, adapting to different site needs. The surface is treated with pickling phosphating + electrostatic spraying or hot-dip galvanizing, which is rust-proof and corrosion-resistant, and can adapt to complex warehouse environments such as humidity and dust. The service life can reach 10-15 years, without frequent maintenance, reducing the warehousing operation cost. It is equipped with a complete safety protection system, including guardrails, anti-skid floor slabs, special stairs, etc., which meets the steel structure design specifications and is safe and reliable. Directly supplied by the manufacturer, it supports bulk purchase and personalized customization, and provides free design, CAD drawings and on-site installation guidance services to meet the warehouse expansion needs in one stop.
