PLASTIC ROOFING SHEET

• HIGH STRENGTH

• HIGH DURABILITY

• LIGHT WEIGHT CONSTRUCTION

• EXCELLENT THERMAL INSULATION

• IN RESTAURANT – EASILY ESCAPE THE HEAT FROM THE KITCHEN

• OPTIMUM PROTECTION AGAINST RAIN & ADVERSE CLIMATIC CONDITIONS.

• IN GARDENS, PARKING

FIBER GLASS ROOFING SHEETS

• IT ALLOWS UNIFORM DIFFUSED LIGHT

• CAN BE USED WITH ASBESTOS CEMENT, GALVANISED CORRUGATED ROOF SHEETS

• IT IS DECORATIVE & ENHANCES THE BEAUTY OF THE ROOF.

USES:

• PLENTY OF NATURAL LIGHT

• IN GARDENS, TERRACE, OPEN TO SKY AREAS, FACTORIES, COLD STORAGE.

• MESH WIRE CAN BE USED FOR EXTRA STRENGTH.

TRUSSES

• A TRUSS IS ESSENTIALLY A TRIANGULATED SYSTEM OF STRAIGHT INTERCONNECTED STRUCTURAL ELEMENTS

• IT IS SOMETIMES ALSO REFERRED TO AS AN OPEN WEB GIRDER.

• THE INDIVIDUAL ELEMENTS ARE CONNECTED AT NODES; THE CONNECTIONS ARE OFTEN ASSUMED TO BE NOMINALLY PINNED.

• THE EXTERNAL FORCES APPLIED TO THE SYSTEM AND THE REACTIONS AT THE SUPPORTS ARE GENERALLY APPLIED AT THE NODES.

• THE PRINCIPAL FORCE IN EACH ELEMENT IN A TRUSS IS AXIAL TENSION OR COMPRESSION.

THE MAIN REASON WHY TRUSSES ARE USED:

LONG SPAN

LIGHTWEIGHT

CONTROLLED DEFLECTION

OPPORTUNITY TO SUPPORT CONSIDERABLE LOAD

TRUSSES ARE WIDELY USED TO SERVE TWO MAIN FUNCTIONS.

TO CARRY THE ROOF LOAD

TO PROVIDE HORIZONTAL STABILITY

TO GET AN EFFICIENT LAYOUT OF THE TRUSS MEMBERS BETWEEN THE CHORDS

THE FOLLOWING IS ADVISABLE:

THE INCLINATION OF THE DIAGONAL MEMBERS IN RELATION TO THE CHORDS SHOULD BE BETWEEN 35° AND 55°

POINT LOADS SHOULD ONLY BE APPLIED AT NODES

THE ORIENTATION OF THE DIAGONAL MEMBERS SHOULD BE SUCH THAT THE LONGEST MEMBERS ARE SUBJECT TO TENSION .

TYPES OF TRUSSES

• KING POST TRUSS

• QUEEN POST TRUSS

• HOWE TRUSS

• PRATT TRUSS

• FAN TRUSS

• NORTH LIGHT ROOF TRUSS

• QUADRANGULAR ROOF TRUSS

• LARGE SPAN ROOF TRUSS

KING POST ROOF TRUSS QUEEN POST ROOF TRUSS

•King Post Truss is a wooden truss. •It can also be built of combination of wood and steel. •It can be used for spans up to 8m.

•Queen Post Truss is also a wooden truss. •It can be used for spans up to 10m

HOWE TRUSS

•It is made of combination of wood and steel. •The vertical members or tension members are made of steel. •It can be used for spans from 6-30m

PRATT TRUSS

•Pratt Truss is made of steel. •Vertical members are tension and diagonal members are compression. •It can be used for spans from 6-10m

•It is made of steel. •In Fan Trusses, top chords are divided into small lengths in order to provide supports for purlins. •It can be used for spans from 10-15m.

FAN TRUSSES

QUADRANGULAR ROOF TRUSSES

LARGE SPAN ROOF TRUSSES

NORTH LIGHT TRUSS • USED FOR SHORT SPANS IN

INDUSTRIAL WORKSHOP-TYPE BUILDINGS

• ALLOW MAXIMUM BENEFIT TO BE GAINED FROM NATURAL LIGHTING

• THE USE OF GLAZING ON THE STEEPER PITCH WHICH GENERALLY FACES NORTH OR NORTH-EAST TO REDUCE SOLAR GAIN.

USES: • INCREASE NATURAL DAYLIGHTING • REDUCE THE OPERATIONAL

CARBON EMISSIONS OF BUILDINGS • REDUCE THE REQUIREMENT FOR

ARTIFICIAL LIGHTING • REDUCE THE RISK OF OVERHEATING

GREEN ROOFS / ECO ROOFS

USES: • SAVES WATER BY HARVESTING RAIN • REDUCES HEAT ISLAND EFFECT • LOWERS SURFACE TEMPERATURE • REDUCES THE ROOF MAINTENANCE COST • CONTRIBUTES TO BIODIVERSITY • FILTERS AIR POLLUTANTS

• A PLANTED ROOF TOP THAT PROVIDES BENEFITS OF WATER HARVESTING, STORM MANAGEMENT, POLLUTION ABATEMENT AND AESTHETIC VALUE. • EXTEND THE EXPECTED LIFE OF THE ROOF’S BASE MATERIAL.

GREEN ROOFS IN HOUSES:

ACCESSORIES NEEDED:

TURBO VENTILATORS

RIDGE VENTILATORS

SKYLIGHTS

INSTALLATION PROCESS

• METAL ROOFING SHEETS

• GRP ROOFING SHEETS

• GREEN ROOFS/ECO ROOFS

POLYCARBONATE ROOFING FIBER GLASS ENCLOSURES

Polycarbonate enclosures can withstand over 900 pounds of impact

Impact resistance is 4 times less

Maintains shape,colour,strength when Exposed to UV RAYS.

It fades over time and UV RAYS makes the material to deteriorate.

More easily modified to different shapes Less flexible

They are marine friendly – resistant to salt water , direct water spray..

Should be careful while using water on it

cleaner look than fibreglass When a hole is cut , the same material cant be used as a lid ,window,etc..
