Exterior Cladding provide a weather tightenvelope.

Transfer Structural Loads I.e. wind & liveloads to the supporting secondary framing.

Provides lateral bracing to the roofs purlins &wall girts.


6/40

Purlins & girts receive loads from the roof & wall

covering & transfer to the main building frame.

Purlins & girts provide lateral bracing to the building

columns & rafter preventing lateral bulking of thecompression flanges.

Moment resisting frames provideslateral stability & transfer the roof & wall

loads to the foundation through anchorbolts.

Roof & wall cross bracing provides longitudinalstability to the building.

Transfer of the wind loads acting on the buildingend walls to the foundation.

COMPUTERISED DESIGN ALLOWED BLDGS TO BETAILORED TO INDIVIDUAL CUST. REQUIREMENTS

ROLL FORMING LINES ALLOWED CONTINUOUS SPAN COLDROLLED Z-PURLINS

COLOR COATED PANELS AND FACTORY INSULATEDPANELS IMPROVED ARCHITECTURAL APPEARANCE

MAJOR INCREASE IN DESIGN POSSIBILITIES CONTRIBUTED

TO THE BOOM IN METAL BUILDINGS

Pre Engineered Building System is computer

assisted, and design to create a building for a

specific use.

The complete building system is Pre Engineered

to facilitate easy production & assembly on site.

In PEB System a superior corrosion protection ofa thin coating of resin applied on the top of theAluminium Zinc coating make Galvalume sheet.

Galvalume steel is a steel sheet product with ahighly corrosion resistance steel, aluminium zinc

alloy hard dip coating.

A clear organic acrylic resin coating is then

applied & then thermally cured.

A colour coating is given on the top surface for a

bright appearance with a colour of thecustomers choice.

PEB System is zero maintenance & superior instrength.

It is corrosion resistance & feature an attractiveappearance.

Steel arriving at job site is dry with no residual oilon the surface.

PEB System has protection against non uniform

weathering.

Excellent resistant in transit to corrosion &storage strain.

This system reduces energy loads on buildingsdue to long term bright surface that helps toretain heat reflectivity.

It is a higher level technology & innovation &

better product over conventional material.

The Galvalume sheet manufactured in theworkshop are colour coated & fabricated bycutting to required length & pressing to desiredprofile as per prepared drawings.

The fabricated sheets & structural memberswere transported to the site of work within aperiod of one week after fabrication.

The profiled sheets were positioned in roofing &cladding & fitted on to the structure using selftapping stainless steel screw with neoprene

washer & then covered with PVC caps of thesame colour as that of the colour coated sheets.

The roof monitor was also provided along withstainless steel bird mesh fitted in steel frame.

The roofing system has 5 % of polycarbonatesheets for the natural day light pass into theworkshop specially ordered & manufactured tothe same profile as that of galvalume sheet.
