- Standing Seam Roofing Sheet
For the most demanding application BIPL offer Standing Seam roof panel. This high performance roof system boasts the highest wind up lift resistance.
A unique one piece GI clip design allows for unlimited thermal movement. Side joints are double lock-seamed to ensure weather tightness. This panel is specially designed for leak proof factory sheds and these panels are formed at site to yield continuous long length panels as per the project requirements.
Technical Data
- ASTM A 653 – Standard specification for steel sheet, Zinc coated (Galvanized) or Zinc- aluminium alloy coated (Galvalume), Pre painted, Bare (un painted).
- Thickness : 0.40mm to 0.8mm
- Panel coverage : 480mm
- Attachment : Concealed clip for thermal movement.
- Trapezoidal Roofing
Features & Benefits
- Designed to cope with the forces of expansion and contraction. This is accomplished by allowing the panels to freely move up and down the roof slope.
- Sliding clips allow thermal movement on a wide variety of building widths.
- Field seamed, hidden fasteners joinery provides maximum protection against the elements.
- The additional small rib design provides added strength against potential foot traffic damage.
- Composite Roofing
Composite roofing is a cost effective roofing solution with respect to its exceptional performance advantages which uses mixture of commonly used roofing material includes various layers like Bottom Sheet (Liner Sheet), Insulation, Top Sheet, Vapour Barrier, TPO Sheets, Acoustic Tissue Paper and so on depends on project requirement and location of the project.
Composite panels are very versatile with a variety of colour, finishes, and accessories, profiles wide range of coatings and insulation thickness and trims with hidden fasteners. On site fabricated sandwich panel provide better and economical solution even when compared with installation case.
They also have guaranteed structural thermal performance, soundproof roof. This is unique for industries requesting cool rooms, sound insulation and heat insulation. ldeally suited for Commercial, industrial projects, Airport Projects.Converting counters delivering a fast and economical installation.
Types of Composite Roofing
The system includes G. I. wire mesh, thermal insulation (Glass wool /Mineral wool) and Top Sheet. Due to insulation solar heat of roof is reduced by approx. 60% inside premises.
- GI Wire Mesh
- Insulation with Aluminium Foil Facing inside
- Top Sheet
This system consists of Inner sheet, z spacer which is fixed along with purlin. Insulation (Glass wool/ Mineral wool) and Top Sheet. This type of roofing can be used for roofing and cladding.
- Liner sheet (Roof or deck)
- Sub girth Z/ Hat sections
- Insulation (With or Without Al foil)
- Top Sheet
This system includes various optional layer including Inner Sheet, Insulation, Outer Sheets, Cement Board, TPO Sheet, Vapour Barrier, Acoustic Tissue and Deck Sheets as per project requirement, project location.
This layer can be customized as per consultants, client requirement to suit project requirement.

- Purlins
Purlins are the secondary, yet the most important member of pre-engineered.building.
In place of conventional channels & angles Z &C purlins are most cost effective & easy to manufacture & install.
Purlins are available from 100mm -300mm depth/height and 45mm to 85mm wide in several thìckness with downturn lips ( flanges)

Hot rolled (H.R) Cold Rolled (C.R) Galavnised | 1mm to 4mm | 245MPA &350MPA | 90 GSM TO 550GSM |
Features
- Fabrication & installation is easy, time saving and cost effective.
- Gives Additional stability in lateral direction to the shed
- Excellent finish & elegance as compared to conventional channels.
- Sleeved Purlins system ensures durability & rigidity of structures
- Saves Cost ,in comparison to be conventional hot rolled purlins
- On site manufacturing possible.
- Decking Sheets
Trapezoidal Metal Profile sheets with strong and reliable shear bond Performance which is augmented by cross embossing located in the profile.
The composite floor profile offers the ultimate in the light weight steel decking which reduced concrete usage to provide a cost effective and alternative floor solution that easy to install. The floor is constituted bya profiled sheet onto which a layer of concrete is poured.
The sheet is bonded to the concrete by means of mouldings on the sheet which stop the concrete from slipping horizontally and detaching vertically. When the concrete is poured and until it has reached an appropriate level of hardening (stage 1), the weights of the concrete, personnel working and equipment used in borne by the sheet alone. Once the concrete has hardened (stage 2) the sheet and the concrete form a unified bond.

Roof Turbo Vent
Effective ventilation is an important aspect of a productive force. Fresh air makes people feel more active and vital, whilst state hot air causes people to feel lethargic and disinterested. The mechanics involved in the air movement is very simple. The hot air inside the shed tends to rise up. When the turbines rotate, they suck the warm air out through the vent, thereby, bringing out a drop in temperature in the shed and allow supply of fresh air through doors and windows. The size, number and installation all depend on different factors which include wind velocity, temperature differential, environment conditions, and the size of the building. Turbine vents have been vastly used for many years in residential, agriculture, industrial buildings and warehouses.
