Main Frame: Two upright posts (One upright post includes two posts and several diagonal tension rods.) Beam (Two beams are required per level.) Decking (The decking is placed above the two beams.) Subframe: Two upright posts (One upright post includes two posts and several diagonal tension rods.) Beam (Two beams are required per level.) Decking (The decking is placed above the two beams.) Pole Holes (Different types of shelves use different hole patterns for beam attachment.)

Medium-duty shelving, a type of storage shelving, falls under the category of rack shelving. It is differentiated and named based on the load-bearing capacity of the shelves. According to this classification, medium-duty shelving is positioned between light-duty and heavy-duty shelving.,Medium-sized货架. Typically, the shelf can bear150kg/-600kgLayer (The load capacity of shelves is mostly calculated by layers). Rack Structure:1The beam and pillar panels are assembled to form a frame, with steel deck plates laid down, thus creating a complete set of medium-sized shelving.2All components of the shelves are processed, shaped, and then assembled into finished products after being polished, pickled, phosphated, and coated with a full-automatic powder electrostatic spray, followed by drying. The finished shelves have a smooth and attractive surface; the shelf layers can be adjusted up and down as needed.50mmAny pitch adjustment, easy to disassemble.3The shelf uprights are formed by cold rolling steel sheets through a cold bending machine, with double-row holes punched on the front face of the uprights, the distance between the holes being50mmThe posts are spaced along a straight line; the hole in the posts is used for hanging the crossbeams. The two posts are positioned opposite each other, with a transverse connection pipe and inclined connection pipe connecting the two posts to form a shelving unit.  Standard medium shelf uprights.4Shelf beams are made of“P”Hollow bars, also known as“Step beam”The step height matches the shelf height.5The shelf steel deck panels are made by cold-rolled steel sheets, bent to the required size on all four sides.Main Frame and Sub Frame:

The main frame and sub-frame medium shelves are assembled from columns, beams, and shelves. A set consisting of two columns is called a main frame. If several sets are assembled into a row, except for one set requiring two columns, the others can share one column with the set in front of it, which is called a sub-frame. This approach saves space and reduces costs, offering greater stability than a single set and significantly increasing storage capacity. For shelves that need to be frequently moved, it is recommended to use main frames exclusively. Shelves connected by main and sub-frames must always move with the main frame.Pole Hole Type:Different types of shelves utilize various hole patterns for the hanging of beams. Common hole patterns in today's market include trapezoidal holes, butterfly holes, diamond holes, sprout holes, and V-shaped holes. There is no specific standard for the choice of hole patterns, with most manufacturers selecting according to their own production processes. For medium-sized shelves, trapezoidal and butterfly holes are commonly used. For example, Jiawei Shelving, a representative of the northern shelf industry, often uses trapezoidal holes, which are convenient for stamping, aesthetically pleasing, and also easy for customers to expand. In the south, some manufacturers use their own hole patterns, so customers would need to rely on the manufacturer for shelf modifications.Application Scope: Medium-duty shelving is primarily suited for warehouses storing lighter goods, with each shelf supporting a load of200-500kgMedium-duty shelving's structural advantages and applications: The medium-duty shelving adopts a structural form that combines beams and shelves; medium-duty shelving can bear200-400kgBeams are available in various cross-sectional sizes, with each layer capable of supporting a certain load capacity.200kg-450kgComponents can be freely assembled and disassembled, the height can be adjusted, with an adjustable spacing of30mmMedium-sized shelves feature heavy load capacity, butterfly hole design, free adjustment, and easy installation. Applications of medium-sized shelves; They are widely used, not only for warehouse storage but also for displaying in shopping malls.
