What Is CGI Roofing Sheet?

CGI roofing sheet is short for corrugated galvanized iron roofing sheet, which is a kind of cost-effective building material. With galvanized steel sheet as material, it is profiled into corrugated patterns with a roller mill. The corrugations will increase the strength of the steel sheet. For roofing purposes, the sheets are waterproofing. You can find different designs, including wavy, tile, ribbed, trapezoidal, etc.

How to Estimate the Weight of CGI Roofing Sheet?

Let’s take a 4*12 ft corrugated galvanized steel 29 gauge roof panel for example. The width and length are about 1,219 mm and 3,658 mm. Gauge 29 is about 0.437 mm. It is a very common thickness for roofing sheets. Weight can be calculated by the formula: 7.85*length (m)*width (m)*thickness (mm)+ weight of zinc layer. So it is about 15.3 kg (7.85*3.658*1.219*0.437).

Storage of Corrugated Galvanized Roof Sheet

In order to prevent white rust on galvanized roof sheet, take precautions on galvanized roof sheet after receiving the goods or before using. Here are the methods:

Stacking and protection

1. Environmental requirements: Galvanized roof sheet should be stored in a dry and well-ventilated environment, and should not be exposed to moisture, including condensation.

2. Reasonable stacking: Galvanized roof sheet should be kept flat when stacked to avoid bending or twisting. Galvanized roof sheets of different specifications and thicknesses should be stacked separately for subsequent use.

3. Avoid heavy pressure: During stacking, care should be taken to avoid heavy objects pressing on the galvanized roof sheet to avoid deformation or damage.

4. Rain and sun protection: If the galvanized roof panels need to be temporarily stacked outdoors, they should be covered with rainproof cloth or sunshade nets to avoid corrosion and aging caused by sun and rain.

5. Unpacking and storage: Customers who receive galvanized roof panels should unpack and store them in time after arriving at the destination. Remember not to cover the packages.

Regular inspection and maintenance

1. Regular inspection: Regularly inspect the stored galvanized roof panels to promptly discover and deal with possible problems such as rust and deformation.

If there is slight white rust or spots on the surface, they should be immediately disassembled and dried until the white rust becomes powdery, and then wiped with a brush in time. Use hot-dip galvanized manual self-spray paint for covering spraying, which does not affect the anti-corrosion effect.

2. Cleaning and maintenance: Regularly clean the dust and dirt on the surface of the galvanized roof panels to maintain its surface finish. Use a soft cloth or brush when cleaning to avoid scratching the surface with hard objects.

3. Anti-rust treatment: For galvanized roof panels that need to be stored for a long time, anti-rust oil or anti-rust agent can be coated on their surface to extend their service life.
