A PURLINS is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin. Purlins also appear in steel frame construction. Steel purlins may be painted or greased for protection from the environment.​

In PEB Steel Construction, the term purlin typically refers to roof framing members that span parallel to the building eave, and support the roof decking or sheeting. ... Purlins are most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.


C - Purlins are horizontal structures that are used to support the load from the roof deck or the sheathing. The plane surface of this purling on one side has made it a preferred material for cladding due to its easy installation on concrete structures or steel.

C section purlins are designed to form the walls and floor joists of a building shell structure, making them ideal for supporting beams needed for mezzanine flooring. In addition, our C section purlins can also be used for door framing, roof trimming, window trimming, parapet rails and side rails.

Z - Purlins are made using cold-formed or rolled sheets for supporting roof. The flexible shape of these beams facilitates various designs solutions. These purlins are extensively used in huge roofing solutions such as godowns, workshops, industrials sheds and many more.

SANDWICH PUFF PANELS are made of polyurethane which is usually sandwiched between two metal sheets. Sandwich puff panels are widely used in steel structures in the present day due to their various advantages. PUFF panels save energy costs while increasing the performance of a structure.

Polyurethane foam is one of the major components of pre-insulated pipe supports manufactured at Piping Technology & Products. Polyurethane is different from most plastic materials in that it can be tailored to meet various load requirements of varying applications.

We offer a wide variety of easy-to-fit, low-maintenance, high-performing insulated roof panel systems.

WALL PANELS: Sandwich panels are a modular building material designed to cover buildings and structures. These panels consist of two layers that form the outer structure and ensure form, weather resistance and rigidity. They contain a core that provides thermal and acoustic insulation properties.

A wall panel is single piece of material, usually flat and cut into a rectangular shape, that serves as the visible and exposed covering for a wall. Wall panels are functional as well as decorative, providing insulation and soundproofing, combined with uniformity of appearance, along with some measure of durability or ease of replaceability. While there is no set size limit for a piece of material fulfilling these functions, the maximum practical size for wall panels has been suggested to be about 0.6 to 2.4 m (2 to 8 ft), to allow for transportation
