4. Product installation details:

1) Screws position drawing reference:

2) Installation notes:

● Please wear gloves,when cutting or installing corrugated steel sheets;

● Make sure clean on gloves or hand,otherwise it will be easily mark on galvanized or galvalume or aluminum sheets;

● Using tin snips for cutting;

● If it’s long length,please use steel cutting blade or power nibbler to cut;

● Take care for end cutting and make it clean.

3) Sealant applying:

● Always apply a sealant bead along a continuous line along the centerline of the fastener hole. This ensures that the sealant can seal the fastener during compression.

● Be careful not to entrainment air when using sealants. In particular, do not place a ring of sealant around the fastener hole, because the air entrained in the fastener during fastening will compress and may cause the passage to blow through the sealant, which will hinder the fastener seal.

● Through practice, you will be able to judge the size of beads, so as to avoid extrusion and subsequent cleaning.

● Unsolidified sealants can be removed with a clean dry rag and then dipped slightly in mineral turpentine or liquor. It is best to remove excess curing sealants with plastic scrapers to avoid damaging metal surfaces.

● Avoid any unnecessary sealant on the surface of paint, because silica gel will affect the adhesion of coatings.

● Smear the sealant can be handled by gently cleaning the area with a nonmetallic scrubbing medium.

5. Maintance for steel sheets

Original design, environment of the installation, and maintenance of

the installation is the three main factors that effects on metal sheets lifetime.Maintenance is the biggest factor,so please read the followign details:
