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 :

An effective ventilation system is foremost necessity of industrial buildings. The hot and humid air, added with exhaust gases from different types of machines and the number of workmen on shop floor makes it imperative to vent out stale and contaminated air and constantly refresh the internal atmosphere with intake of 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.

CONTINUOUS AND FIXED LOUVERS:
The Continuous and Fixed Louvers Ventilation System are most effective. The framed louvers are designed to provide water resistance against all weather conditions with innovative baffles which help in minimizing rainwater and dust penetration while maximizing natural air-flow.

Key Features:
It has excellent water and dust resistance.
Easy Installation and Maintenance free.
Technically designed available in customized lengths.
The Louvers allow fresh air to come inside and prevent the entry of dust and rain water.
Removes dampness and humidity.
Corrosion Free.
24 Hours fresh air keeps workers active and healthy.
Available in Galvanized, Galvalume or Colour coated forms.

Benefits:
Zero operational cost : Louvers provide ventilation effect without the consumption of electric power.
Reduced Power costs : Proper ventilation provides a cooler, low humidity working environment,
which reduces the need for costly air conditioning or industrial fans. Negligible Maintenance Costs : The maintenance cost is drastically negligible.

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.

Decking Profile Sheets are used for composite floor system as well as permanent form work. They have strength and positive reinforcement due to their composite design. The input material for Deck Sheets can be PPGI/HR/CR/GI.



ADVANTAGES:
Easy and Fast Installation.
Provides stable working platform.
Reduces weight of concrete floor.
Light Weight and cut to length sizes give easy fixing of studs, clips and screws.

ADVANTAGES OF USING STEEL DECKING:
Decking sheets as prop free shuttering enable obstruction free movement of men and materials that facilitates faster construction.
Floor casting can be carried out simultaneously on many floors.
Decking sheets provide a safe and strong platform for movement of construction crew.
When used as composite floor deck, provide structural diaphragm support and reduce consumption of reinforcement steel.
Relatively lower grade of cement and thinner slabs can help achieve cost savings without compromising design needs.
Full-floor covered with steel decking enables high speed slurry pumping and reduce manpower deployment Special, skilled manpower for floor casting and shuttering is no longer needed.
Floor decking and concrete casting can be carried out on multiple floors.
Huge savings in construction time.
Speedier construction and faster completion results into speeded up revenue stream.
Time saved is money earned by earlier than scheduled commissioning of the premises.
Concrete grades M-100 to M-200 with steel decking need no re-bars for slab reinforcements. Wire mesh is enough.
