"Storage shelves" in the main sub-frame presentation: storage shelves by columns, beams, assembled from plywood, a separate set of two columns, if assembled into a few groups, then in addition to the first group requires two column, the other in front of it can be a group of one column. So you can save space and reduce costs, strong robust performance than a single group, so that storage capacity is also greatly improved. It can be described as both save money and effort.
When the shelf procurement, quoting from the shelves which provides manufacturers often "main frame, sub-frame" and some shelves vocabulary. If you do not understand these technical terms, they tend to be some of the black heart of manufacturers earned away should not spend money. Although the word, there is not a small price difference. So, what the main frame? What is the sub-frame where? You just below explain in detail.

Refers to the lack of a column, attached to the main frame, the shelves need not be a separate connection. If the four shelves assembled into one, then formed "a primary Secondary" shelf combination. In addition to the first group needs two columns (the main frame), the other can share it in front of a group of a column (auxiliary frame).

Application Advantages

Main sub-frame connection can not only save space and reduce costs. Solid performance is also greatly improved than stable, so the storage capacity of a single group. For example: a combination of two independent storage shelf needs four columns, but combine them into one, you only need three columns, you can save a post. The more the number of connections, the more savings uprights.

For example: two independent medium-sized storage shelves need eight columns, but put them into one, only six columns only. The more volume, the more favorable for the customers.

Security, storage shelves appeared, bringing greatly enhance security, including the safety and cargo security, traditional storage rack body single Li Bo, with a long time will be a variety of problems, while the use of storage shelves The new technology, surface spray treatment, waterproof rust.

Technical aspects of the production, storage shelves production technology compared to traditional angle shelf technology has greatly improved, storage shelves using the hook-type assembly, installation and removal is very convenient.

Clear classification, storage shelves into heavy, medium and light. Depending on the weight of the goods to the rational design of different types of storage shelves.

Easy installation, storage shelves using hook type, between the beams and columns and hanging hole by hooking, installation and removal is very convenient. Can produce multi-layer shelf, the upper and lower spacing can easily adjust the size.
