Steel material boxes are generally made from steel or galvanized steel sheet, welded by CO2 gas-shielded arc welding, with a galvanized or electrostatic powder-coated surface. They store goods conveniently and, when not in use, can be folded to save fixed space and reduce storage costs.
Thanks to their material properties, steel material boxes are strong in load capacity, require no maintenance, have a long service life, a sturdy chassis and high overall rigidity. On shelving they have a high friction coefficient, do not slide easily under load, and are safe and reliable to use — good rigidity, large load capacity, durable and long-lasting. Forklifts can enter the box from all four sides, improving space utilization and operating convenience.
The bottom of a steel material box adopts a rigid frame structure welded from steel panels and steel legs. The four upper side panels of a box-style steel box are welded from corrugated plate or flat plate. The upper part of a mesh box uses the same cold-drawn wire and profiles as warehouse cages. The frame is usually built from rectangular or square tubes welded together; posts are generally square tubes or angle steel, with hanging ears welded to the top for stacking or lifting. Surface treatment uses shot-blasting to better remove rust and oil, meeting export requirements for steel material boxes. A later high-temperature (180-degree) spraying-and-baking process gives the product a tidy, attractive and durable finish.
Steel material box dimensions can be made to a customer's actual product requirements. When purchasing, consider the outer dimensions of the products to be placed, that the designed load must meet usage requirements, whether the box is for storage or turnover, and whether stacking is needed. In general, the steel material box manufacturer will design drawings to the user's actual needs.
