The installation rules of TOP pc solid sheet (Cutline)

1. Installation by inserting

A. Because the protective film inserted in supporting frame has a bad affect on adhesion between crack filler and PC panels, protective film 5-10mm wide inserted should be cut off before PC panels are inserted.
B. Since the expansion and contraction degree of PC panels are different from the metal frame, as well as PC panels are flexible and taking air pressure, therefore, appropriate insertion, reserving space for expansion and shrink, and choosing suitable thickness of PC sheets are necessary. General plate should be inserted into fixed frame for over 2.5cm, 3mm place will be reserved for expansion or shrinkage.




2. Installation by screws
A. For any outdoor installation or installation in environment with temperature difference of 40℃, aperture of any bolt or rivet much be enlarged to allow PC panels expanding or shrinking with change of temperature. Generally, the aperture shall be 50% bigger than the diameter of bolt. Use aluminum rivet. Self -drilling screw must be abandoned.
B. Use silica gel to fill all apertures and cover their exposing parts to prevent PC panels from map cracking by cleanser which may inserted in apertures.
C. The head of rivet should be 1.5-2.0 times bigger that the stem. Use gasket to fill between PC panels and rivet head to prevent PC panels getting direct pressure from rivet head, then lessen their pressure in this way.
D. Don't tighten screw too much in case stress may cause thereof.
E. Don't use PVC gasket and water-proof adhesive tape with as phal content.
F. Fix the metal pressing strip on long and short edges of PC panels. Remain a space for their expanding. Strengthen installation stability.





The installation rules of TOP pc hollow sheet. (The installation way is same with PC solid sheet)

1, Installation by Sealant.



2, Installation by insert.




Notice in installation:

(1). Fill up the holes, and cover the exposed portion with silicone compound to prevent detergents permeating which brings damage to pc sheets, and avoid gradual cracks.
(2). Rivet heads should be larger than the stems by 1.5~2 times. Use gaskets or washers to avoid the rivet heads touching pc sheets, and reduce the pressure.
(3). Do not screw into too tightly.
(4). Do not use gaskets made of PVC.
(5). The bending part should be avoided using screw for cold bending process. Key points for bending processing and design under normal atmosphere temperature.

Other advise:

(1).Cutting: The pc hollow sheet can be cut by sharp reamer, and the solid sheet can be cut by fretsaw, band saw and handsaw, but you should to peg the solid sheet in order to avoid librating when you're cutting the solid sheet, clean up the sawdust after you cut the sheet.
(2). Drill: The pc hollow sheet can be drilled by aiguilles; the aiguilles diameter should be longer than the screw diameter in order to adapt the temperature change. Otherwise, it shall not to drill 40mm from the edge of the pc sheet.
(3). Both sides on both hollow panel and solid panel are all covered by protect film. In order to keep the surface smooth, please do not take off the film before finish installation. At the process of installation, it could be recovered about 5 CM at the edge part of them.
(4). Please do not put strong goods on the panel and keep the sharp things on them during transportation.
(5).UV coating side of pc sheet must face towards to the sunlight when installing.
(6). Always keep the PC sheet clear, and never walk on the panels.
