Prepainted Coils

First of all, it is necessary to define a concept: what we usually call "prepainted coils" does not appear directly in the form of roll on the finished library shelf, but as the main raw material for manufacturing the shelf. prepainted coils is a series of processing, only become the solid and beautiful bookcase parts we see.

The Core Application of prepainted coils in Library Shelves

prepainted coils have become the preferred material for modern library shelf manufacturing due to their outstanding performance, gradually replacing early angle irons, cold rolled steel plates (requiring later painting) and wood.The application of prepainted coils on the bookcase is mainly reflected in the following aspects:

1.prepainted coils can be used as core structural materials:

·Bookcase side plates (vertical plates), shelves (laminated plates), back plates, top plates and bases: these are the main components of the bookcase. These components are made of prepainted coils with extremely high structural strength and durability.

·Processing process: the factory uncoiled and leveled the large roll of prepainted coils material, sent it to the numerical control punch for punching and trimming, and then bent into the required shape through the bending machine (for example, the bending edge of the shelf can increase the load bearing and prevent the book from sliding), and finally assembled into the book shelf through bolt or buckle connection.

2.The prepainted coils can provide excellent durability:

·Corrosion and rust resistance of prepainted coils : libraries require long-term use and sometimes cleaning. prepainted coils base plates (usually galvanized steel sheets) and surface coatings (polyesters, silicon-modified polyesters, etc.) provide dual rust protection, effectively resisting humidity in the air and daily wiping, with an extremely long service life.

·Scratch and abrasion resistance of prepainted coils : frequent picking and placing of books and occasional collision of carts have abrasion requirements for the surface of bookcase. High-quality prepainted coils have high surface hardness, are not easy to leave scratches, and can be kept beautiful for a long time.

3.The prepainted coils can realize aesthetics and functionality:

·Rich color selection of prepainted coils: this is the biggest advantage of "prepainted coils ". The library can choose the color of the bookcase according to the overall decoration style, such as stable walnut grain, coffee color, dark gray, or bright white, light blue, etc. This helps create a comfortable, modern reading environment.

·The prepainted coils is easy to clean and maintain: the surface is smooth and not easy to absorb dust. It can be cleaned with a damp cloth, which is very suitable for the public environment with sanitary requirements.

·prepainted coils is environmental-friendly and pollution-free: compared with the steel bookcase painted on site or the wooden bookcase requiring anti-corrosion treatment, the color coated roll has been painted in the factory, without peculiar smell and formaldehyde release, which is more environmental-friendly.

4.Design flexibility and standardized production of prepainted coils:

·prepainted coils can be easily machined into various sizes and specifications to meet the different requirements for shelf height, depth and number of storeys in different areas of the library (such as common reading area, children's area and dense library).

·The standardized production components of the prepainted coils allow the bookcase to be combined in a modular manner for future expansion or relocation.
