 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 .

Contd…..

 In

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

 Galvalume

steel is a steel sheet product with a highly 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 the customer’s choice.

is corrosion resistance & feature an attractive appearance.

 Steel

 PEB

System has protection against non uniform weathering.

 Excellent

 This

system reduces energy loads on buildings due to long term bright surface that helps to retain heat reflectivity.

 It

is a higher level technology & innovation & better product over conventional material.

 The

Galvalume sheet manufactured in the workshop are colour coated & fabricated by cutting to required length & pressing to desired profile as per prepared drawings.

 The

fabricated sheets & structural members were transported to the site of work within a period of one week after fabrication.

The profiled sheets were positioned in roofing & cladding & fitted on to the structure using self tapping stainless steel screw with neoprene washer & then covered with PVC caps of the same colour as that of the colour coated sheets. The roof monitor was also provided along with stainless steel bird mesh fitted in steel frame. The roofing system has 5 % of polycarbonate sheets for the natural day light pass into the workshop specially ordered & manufactured to the same profile as that of galvalume sheet.

Contd… 

The roofing system in PEB is latest product & since it is made of steel, it is easier to maintain compared to the conventional Sheets.



It is lighter than conventional Sheets.



The colour coated steel Galvalume sheets can also be padded with rock wool or a similar product which can keep a difference of inside & outside temperature by about 8 Degree centigrade which is not possible in conventional Sheets.This renders better comfort to the people working within thereby increasing the productivity also.
