Technical Specifications of Corrugate Sheets

 

Technical Specifications of Corrugate Sheets:

Considering the need of light transparency and improvement of consumption of energy, resistance to bad weather, economical savings and special mechanical properties; flexibility, light weight and high security and easy installation J.Lian J Company has produced a new product under the name of corrugate. In the following specification of these sheets has been discussed;

 

Both sides of the Corrugate Sheets are covered with protective surface coating film. On the side that is resistant to UV rays instructions of installation and maintenance of the sheet is printed.

Installing Polycarbonate Corrugate Sheets:

Considering Safety Issues during Installation:

Do not put your foot on the sheets during installation. Other Safety matters shall be considered during installation.

Resistant to Impact from Inside:

Corrugated Polycarbonate Sheets have high impact resistance but if used in sport halls it shall have an additional protector such as metal screen or three layered triangle sheets with thickness of 10-12 of polycarbonate which are used underneath them.

Method of Installation on the Roof

General Guide

Infrastructure (Beaming)

Metal: Profile (box) 4*8 to 4*4 or aegis (T form) and/or Z and/or IPE

Wooden: 4 cuts of 6 cm maximum width and 8 cm maximum height

Method of Cutting Polycarbonate Sheets:

Polycarbonate Corrugated Sheets can be cut to desirable sizes with a manual or vertical electrical saw with small jags (5 jags in cm).

Longitudinal Overlap:

The longitudinal overlap of the sheets shall stand on the poles. The overlap shall be at least 15 cm for all kinds of polycarbonate sheet.

Latitudinal Overlap:

Latitudinal overlap shall be against the general side of the wind in the area and the amount of it depends on the kind of the sheet.

Method of Screwing the Polycarbonate Sheets:

Place of holes for installing the sheets as walls are inside the arch of the corrugation.

Place of holes for installing the sheets as roof are on the arch of the corrugation.

The distance of the edge of the sheet from the first screw shall be less than 5 centimeter.

Drilling shall be performed efficiently with electrical drill. It shall be mentioned that the drill shall be sharp. The diameter of the hole shall always be approximately 4 millimeters bigger than the screw.

-For good performance of the gaskets the inside and around the holes shall be completely clean and without dust.
-The screws shall be tight enough to prevent leaking but it’s necessary to keep enough space for expansion of polycarbonate sheets.
-Never install polycarbonate sheets with nails. Using nails on these kinds of sheets are strongly restricted.

Corrugate Polycarbonate Sheets have the characteristics of auto turn-off. They are applicable in 40-120oC. They have brilliant light specifications and impact resistance which is approximately 120 times more than normal glass. They are resistant to most of the chemical materials and solvents. Polycarbonate sheets are good replacement for glass applications. Light weight equal to ½ of glass with same thickness, easy transport and installation, resistance to direct fire class B1 are few of its virtues. To these we should add its good insulation of heat and sound.
