Pre-Engineered Buildings consist of different steel-structural-members:
Purlins | Eave Struts | Side Runners | Fascia Channels | Door Posts | Window Posts | Rafters Stays | Column Stays | Base Angles Cold-formed "Z" and "C" shaped secondary structural members are Cold Roll Formed light gauge, which are made as per the design requirement and consists of: Roof Purlin | Eave Struts | Well Girts
The sheets and panels provided by us are of Galvanized/Galume aluminium/Stainless steel, Cold rolled low carbon steel coils. They are of Two Coat, two Back Colour Coating Line of RMP/SDP/PU/SMP/PVDF/Plastisol Paint, solvent & Water Base PU & Polyester Guard Film.
They consist of:
BUILT-UP “H” SHAPED PRIMARY STRUCTURAL FRAMING MEMBERS COLUMNS RAFTERS
These are fabricated from high strength grade plates, cut to size and shape as per specifications and used in making Built-up sections. Any geometrical frame is possible in this system. Unsymmetrical framing systems about the ridge line and multiple framing systems with unequal width are also possible, but with more engineering time and longer delivery periods. All components are designed for compatibility. These components are fabricated under strict quality control norms as per shop drawings. Functional subsystems include mezzanine floors (including joists and decking), crane runaway beams (to support crane systems), roof platforms, catwalks, etc. Aesthetic features include fascias, parapets, canopies and roof extensions. These components are transported and assembled at site as per erection drawings
Secondary members are composed of roof purlins, wall girts, eave struts and roofing sheets. Roof purlins, wall girts & struts are forms of Z-purlins, C-purlins and hollow sections. Z--purlins & C-purlins are cold formed steel members having a minimum yield strength of 345 MPa with zinc coating (120/180/275 gsm)
Purlins are Z sections with 200 to 300 mm depth & thickness from 1.75 to 2.50 mm as per requirement. They are fixed to the top flanges of the rafters by means of cleats moulded to the rafters and the purlin web bolted to the cleats. Purlin ends are overlapped to act as continuous beams.
Purlins come in 96 x 48 to 172 x 92 mm sizes and thickness from 3.0 to 4.8 mm as per requirement. They are fixed to the top flanges of the rafters by cleats moulded to the rafters and bottom bolted to the cleats and flushed with webs of the rafter resulting in a stronger structure.
Wall Girts shall be Z sections with 200 to 300 mm depth and thickness from 1.75 to 2.50 mm as per requirement. There are two fixation methods:
These girts are fixed to the outer flange of the side wall column by cleats moulded to the side column and the girt web bolted to the cleats. Overlapping connections are provided for continuous beam.
End Wall Girts and Flushed Girts on side walls are flushed to the outer flange of the columns by cleats bolted to the column web and the girt web bolted to the cleats.
Girts are hollow sections with 96 x 48 to 172 x 92 mm sizes and thickness from 3.0 to 4.8 mm as per requirement.
These girts are fixed to the outer flange of the side wall column by cleats moulded to the side column and the girt horizontally bottom bolted to the cleats
End Wall Girts and Flushed Girts on side walls are flushed to the outer flange of the columns by cleats bolted to the column web and the girts horizontally bolted to the bottom of the cleats
Hollow sections are Hot Rolled Formed sections with a yield strength of 310 MPa and UTS 450 MPa
Eave Struts are C & Z sections with 200 to 300 mm depth and thickness from 1.75 to 2.50 mm at the rafter ends. The Struts are fixed to the top flanges of the rafters by cleats moulded to the rafters and the struts web bolted to the cleats. Strut ends are overlapped to act as continuous beams.
Eave Struts are hollow sections with 96 x 48 to 172 x 92 mm sizes and thickness from 3.0 to 4.8 mm. The struts are fixed to the top flanges of the rafters by clips moulded to the rafters and bottom bolted to the cleats and are flushed with web of the rafter resulting in a stronger structure.
Roof sheets are cold formed with yield strength of 550 MPa
Roofing sheets made of metal are used for pre-engineered building solutions. They are 12 m+ in a single length and are self-drilled through fasteners. They are applied for roof slopes as low as 1:20 and are applied as internal lines for double skin roofs and wall constructions without insulation. They can be curved to attain an aesthetic, architectural look.

These are velocity driven and centrifugal force generated, creating a low pressure area which draws out stale, damp and hot air through the ventilators and fresh air is automatically replaced. Turbo ventilators are wind driven, energy saving, pollution free and are virtually maintenance free.
Louvers maintain a regular flow of fresh and natural air in the industrial and storage areas. In combination with Turbo Ventilators, they help in reducing the build-up of dust, vapour and heat inside the building.
Flashings and Trims create harmony and splendour of the pre Engineered Building Structures. These sheet metal closures are designed to protect from weather effects with neat appearances at corners and junctions.
The nuts & bolts provided by us are self-drilling, self-trapping screws & fasteners, which are coated with a combination of Tin-Zinc coating which is mechanically deposited. This coating prevents the accumulation and formation of impurities, moisture, rust, and electrical current, on and around the steel/metal surface.
The FRP sheets provided by us are water resistant, non-combustible, and environment friendly. As they are translucent and transparent in nature, they save drastically on the electricity bills.

According to the world green building council, “a ‘green’ building is a building in its design, construction or operation, reduces or eliminates negative impacts and creates positive impacts on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life.”
Pinax Group also specialises in Green Buildings that are designed, built, renovated, operated, or reused in an ecological and resource efficient manner. Green buildings help protect occupant’s health and improve employee productivity. Using energy, water and other resources more efficiently, we reduce overall impact to the environment and optimise environmental and economic performance.
