Ravftor Hi-Rib Trapezoidal Profile is a high tensile wide cover width versatile roof and wall cladding profile sheet. Hi- Rib has a bold, deep toughed profile that is able to fixed down to 1o pitch and can achieve up to 2.0 metre (multiple) spans for roofing with enhanced performance under both Point Load and Distributed Load.
These sheets are produced on state of the art machines ensuring extra strength and perfect over-lap providing a high degree of weather protection and corrosion resistance. The profiled sheets are large, lightweight and easy to install, not to mention very economical. They create a rigid, ribbed, aesthetically pleasing surface, and satisfy the roofing requirements for many types of property, ranging from residential to public and commercial buildings. The input material for this profile can be :

Roof Mounted Air Driven Ventilators with Polycarbonate and F.R.P. base plate are wind driven natural Ventilation system. These ventilators expels hot, humid and moisture laden air from industrial buildings and provide a more comfortable clean working environment replacing summer heat and winter dam p with fresh air.
Natural Ventilation systems suits best by synergizing the exhaust through Roof mounted air driven ventilators, and fresh air intake via Louvers mounted on side walls.
Features:
Maintenance free and rotates freely due to the permanently lubricated bearing system.
Easy to handle and install with a variable pitch base, fitting all tile, metal and fiber cement roofs with pitches upto 450.
Removes dampness and humidity.
24 hour fresh air keeps workers active and healthy.
Benefits:
No Operating Costs: Having a self contained wind powered design, there are no operational cost incurred.
Reduced Power Costs: Proper ventilation provides a cooler, low humidity working environment, which reduces the need for costly air conditioning or industrial fans.
Reduced Installation Costs: Due to the versatility of the variable pitch throat, installation costs are reduced as one
unit fits most industrial application (00 to 22.50).
Income Tax Benefit: Ventilators are 100% depreciable under Income tax laws giving huge benefits.
Reduced Maintenance Costs: Rising damp and humidity cause corrosion of building structures, painted surface,
metal fittings and electrical wiring. Proper ventilation eliminates these problems.
Common Uses:
Roof ventilation system is meant for warehouses, factories and workshops, Gyms, Tennis courts, Assembly halls, garages, toilets, laundries etc.
Calculating How many VENTILATORS:
Determine the volume (VOL) of the building in cubic meters. (Length x Width x Height)
Dependent on the building type, select the required Air Changes (A/C) per hour, from the table below
From local authority records, determine the typical wind sped, 6, 8, 10,12 or 16 km/h. This will establish the exhaust capacity M3 per Hour (Refer Table).
Calculate No. of Ventilators = VOL x A/C Exhaust Capacity M3/hr.
| Recommended Air Changes (A/C) for Various Building Types: |
|---|
| Building Type | Ideal Air Changes Per Hour |
|---|
| Warehouses | 3 to 5 |
| Workshops | 3 to 8 |
| Assembly Halls | 5 to 10 |
| Garages | 6 to 12 |
