Metal sheet is a square fluted profile with an effective covering width of 820,840,900mm designed for use as side

cladding or roofing material in commercial, industrial and residential buildings. The name IBR is abbreviated from

"Inverted Box Rib" and has became a household name in the foreign market

The deep broad flute design offers excellent drainage characteristics combined with optimum weight versus load/span

capabilities.

Structural guidelines.

IBR roof sheets are available in a wide range of materials displaying various structural properties. It should be noted

that the load span characteristics are only to be used as a broad guideline as purlin spacing is also dependant on other

factors such as the prevailing winds in a certain area, snow during winter periods, the presence of dust and other particles

in industrial areas, the type of structure that is being erected etc.. We therefore recommend that an engineer is consulted

to determine the purlin spacing for a specific application.

Available dimensions

IBR sheeting is available in standard lengths up to 15 metres. The permissible length tolerance for the standard length

range will be -+5 mm. Sheets outside these parameters are available on request and might be subject to special pricing

arrangements. The maximum height which can be transported is 4.3 metres. This factor should be taken into account

when bullnoses and curves are designed.

Roof pitch

When using IBR, the recommended minimum pitch for roof slopes in excess of 30 m is 7.5º and for slopes less than

30 m is 5º. When IBR roof sheets are end lapped the roof pitch should be taken into account. The minimum end laps

for roofs pitches in excess of 15º is 150 mm and for other roofs a minimum of 250 mm is recommended. End laps for

side sheeting should be at least 100 mm. It is recommended that end and side laps on low pitch roofs are sealed to ensure watertightness.

Corrugated sheet roof and wall panel

Corrugated sheet is a new option for roofing and wall cladding construction.

It is tough, durable in color and lightweight, better than metal and galvanized sheet. What's more, it will never rust in heavy industry park.

Why corrugated

Corrugated sheet is often used in the building industry as a low-maintenance material, particularly in Ireland, United Kingdom, and United States where it is known as vinyl, or vinyl siding.

Feature

Corrugated roof sheet is made of prepainted galvanized steel,resistant to acids, fungi and humidity with prominent quality. It remains stable in physical performance of -40°C to 80°C.

The corrugated design not only provides an unique appearance, the sheet itself is also waterproofing, boosting drainage in rainy and snowy area as well.

The anti-corrosion performance of corrugated roof tile is suitable for most applications in coastal areas with severe salt fog corrosion, and the areas with severe air pollution, especially in heavy industrial park.

Application

Corrugated sheet is best installed on industrial building, agricultural building, factory, warehouse, mobile home, manufactured home construction, steel structure, shopping mall.
