While ensuring a good decorative effect for the decorative metal siding, its construction quality is also very important, which is related to its service life. During construction, in addition to strictly controlling the quality of the boards, attention must also be paid to the relevant requirements for its construction accessories.
1. Galvanized light steel keel
(1) The vertical keel of QC100*45*0.7*8 specification can be used for the vertical column of the galvanized light steel keel, and the horizontal keel of QU100*35*0.6*8 specification can be used for the beam.
(2) The shape of the keel should be smooth, the edges and angles should be clear, and the cut should not have burrs and deformations that affect the use of the keel. The galvanized layer must not have defects such as peeling, bruising, and falling off. The surface of the light steel keel has been galvanized to prevent rust. The quality of the keel of this project is excellent, and the amount of galvanizing on both sides is not less than 120g cm*m.
2. Connectors
The fastening iron parts connecting the main keel of the carved insulation board used by China Metal, the connecting parts between the main keel and the secondary keel structure:
The main keel and main keel, the internal and external environmental casings (or connectors) of the main keel, and the sub-keel joints must be galvanized, and the materials and specifications of different sizes must meet the development requirements of teaching design. Classify and store after entering the site.
3. Fasteners
Anchor bolts, expansion tube screws, and rivets are all made of high-quality stainless steel company steel. When entering the site, there must be a factory quality certificate, unpacking, and random inspection.
4. Sealant
There is a factory certificate, and the bonding and waterproof performance should meet the design and construction requirements of the decorative metal siding.
After entering the site, the above materials should be properly stored according to different specifications, and should not be exposed to rainwater.
If the quality of the decorative metal siding is not up to the standard or the relevant requirements, it will also affect the construction quality of the board, which will affect its service life, so the quality of any accessories must also be controlled.
