After receiving the drawings and cutting orders, the factory converts them into equipment cutting lists, maintaining unified numbering and refined management to ensure that the quality and specifications of the air ducts produced are correct.

After the semi-finished air ducts are processed in the factory, they are affixed with coded labels. After the air ducts are processed, they are loaded into trucks according to the codes. The products have corresponding QR codes. Scanning will display the specification information of the corresponding products, making it easier for on-site personnel to quickly find the corresponding materials for splicing.

After the materials arrive, they will be unloaded at the designated area according to the list and inspected according to the list specifications and quantities.

After the materials arrive, they will be unloaded at the designated area according to the list and inspected according to the list specifications and quantities.

According to the QR code information of semi-finished products, find the corresponding materials for connecting seams and corner code splicing.

The four corners of the spliced air duct should be sealed with sealant, and the connecting sections should be sealed with sealing strips

After the air duct is assembled, the air duct should be cleaned, inspected and sealed at both ends in the clean shed to ensure that the inside of the air duct is clean.

The corresponding brackets are prefabricated in advance according to different air duct specifications, and are chamfered and repainted.

Different bracket installation methods are adopted according to the on-site bracket installation position (concrete floor slab, above and below the steel structure, purlins, C -shaped steel, steel cables, etc.)

(An example is a solution for installing air duct brackets when concrete floor slabs or steel column spans are large)

The air duct is assembled with 3-4 connections below, and then installed as a whole.

Install the air duct main pipe, branch pipes, and lower pipes to ensure that they are horizontally and vertically, and add fixed brackets
