PHYSICAL AND MECHANICAL PROPERTIES

Composite Floor Decks feature a galvanized ribbed profile with embossments designed to interlock with the concrete slab. Our professionals manufacture these sheets by quality approved raw materials and cutting edge technology. The deep profile allows a deep and stronger pour of concrete therefore a higher slab depth can be obtained. As with all the floor decking panels the widths allow for easy installation with the male and female receptors. The deck initially acts as a form for the concrete, and after the concrete cures, the deck acts as the positive moment reinforcement.

Available Finish: Galvanized, Cold Rolled (CR)

Uses: Steel Deck performs as a positive reinforcement and a permanent form support, providing savings in concrete and reinforcement steel.


Time effective to install decking panels over a vast area Once fixed, the deck acts as a safe platform Unlike conventional constructions processes, lesser concrete is required It lowers the weight of primary structures and foundations Composite deck flooring is economical and affordable Reduces construction time

The Polyethylene Panel is a product in which the polyethylene foam is formed into sheet form and is applied with a layer of aluminum on the top and the bottom. The metallic surfaces have been prefinished and coil-coated in a variety of paint finishes before bonding. The product can also be attached to pre-painted galvanized steel sheet and is also sold in the form of the sandwich panel. The panels offered are rigidity of heavy-gauge sheet metal in a lightweight panel that’s easy to fabricate and adaptable to a vast range of indoor and outdoor building applications. The minimum width of the panel is 1 meter and the foam thickness is available in the ranges of 6mm and 8mm.

Uses: The aluminum foil skin gives an attractive finished look and is used for brightening the interior of a building such as factories, warehouses, cold storages.

Pre-painted galvanized roofing sheets. In the past 20 years, end-users, contractors and consultants have become increasingly aware of the losses associated with thermal transmission. Insulation of various types is now used in all types of buildings. The insulated polyurethane sheets have a thickness of 20 mm. Liner panels have one metal skin surface with polystyrene foam board adhered to it for better insulation. QSIF is one of the first companies to introduce polyurethane sandwich panels in the Middle-East. Polyurethane has been recognized as the most resistant material to heat transmission.

Uses: These sheets can be successfully applied to cold storage, warehouses, residential villas, houses, covered pools and sports complexes. Moreover, there are various choices of rich colors available both in single skin or double skins.

The features includes:

Resistant to corrosion, deformation and breaking High resistance to water absorption No requirements for interior or exterior finishiing Can simply be disassembled when necessary High insulation value Long service life Strong aesthetic value

INTRODUCTION

Secondary framing is an important component of many pre-engineered metal buildings. Purlins are also referred to as ‘secondary structures’. Most commonly known to be lightweight construction elements manufactured from sheet metal strips. These sheets are available in galvanized C & Z sections.

Supplied plain or punched, galvanized purlins are manufactured from high tensile steel for increased strength, reduced weight, and a long serviceable life. QSIF can manufacture a complete range of structural C and Z purlins and girts for industrial buildings, garages, verandahs, and carports, in fact anywhere that strong, reliable steel framing is required.

C Purlins: C Purlins are used as Purlins over walls, rafters, floor joists and studs for walls.

Z Purlins: This shape helps the Purlins to overlap joint and is stronger and studier than the C purlins. As a result, they tend to be used for large-scale

The features are as follows:

Strong structure Seamless and straight Choices of customized lengths Lightweight makes it easy to handle and transport and also reduces the cost up to 40% The automatic controlled manufacturing ensures close tolerances Fast and quick to install Excellent resistance to corrosion Long-lasting and durable

Material: Galvanized iron wire they are also available in coated PVC.

Weaving: Woven diamond pattern provides strong, durable and flexible construction. Chain links are the most suitable fencing nets for both residential and industrial purposes. Chain link fencing nets are still considered to be one of the most effective methods for providing security and access control. The popularity of chain-link fence is due to its relatively low cost. A further advantage is that, due to the open weave, chain-link fences are transparent and do not obscure sunlight from either side of the fence.

Uses: Diamond mesh is used as fencing for sports field, river banks, construction and residence, also animal fencing.

Features of Chain link includes the following:

It is long-lasting as it resists corrosions due to weather It provides security and protection Can be easily customized for special jobs and purposes Can be availed in different sizes suitable for your needs Minimum requirement of maintenance

MS HOT/COLD ERW RECTANGULARHOLLOW STRUCTURAL SOLUTIONS

QATAR

Rectangular Hollow structural tubes are manufactured from flat steel strips which are formed by continuous sets of rolls. The strips of the edges are heated at big induction welders and then forged together through the welding rolls. Therefore they are produced into longitudinal welds without any filler metals. Then, weld tubes are cooled down and processed through sizing rolls rectangular tubes.


Uses: There is huge scope of this standard – The tubes can be used to support columns and trusses, storage systems, highway guardrails and so on.


Consistent physical features prevent any drastic variations or fabrication The product is well tested with excellent machinability and high strength Insured and tested for quality assurance High resistance to torsional loading Excellent surface condition Wide variety of shapes and wall thicknesses are available Ready and available in our stocks in lengths of 6 meters

MS ERW ROUND HOLLOW COLD/HOTSTRUCTURAL SOLUTIONS

QATAR

MS ERW Round Structural Pipes also known as round steel tubes, are a common type of steel section which are made either from hot rolled, cold rolled or pre-galvanized steel strips formed by a continuous set of rolls. The slit strip of steel coil goes through a forming and sizing section in a normal cold forming steel mill. The mill consists of a number of passes through which the sheet is gradually formed by pass bending the steel sheet more on each pass. This is done until the two ends of the steel is pressed together and then welded inline. The strips of carbon steel are heated at the edge and welded together forming into longitudinal welds, without any filler metals. Then, weld tubes are cooled down and processed through sizing rolls into round tubes.

Uses: There are many advantages and uses of such pipes – they can support columns and trusses, storage systems, highway guardrail construction of bridges, commercial and residential building, and all other structural purposes.




Our tube ranges are equivalent to European and Japanese standards.

MS HOT/COLD ERW SQUAREHOLLOW STRUCTURAL SOLUTIONS

QATAR

Square hollow tubes are cold formed and welded from either hot rolled, cold rolled or pre-galvanized. Hollow sectional structural tubes are manufactured from flat steel strips which are formed by gradually changing its shape through continuous sets of rolls. The strips of the edges are heated at big induction welders and then forged together with welding rolls. During the manufacturing process the mother tube goes through a series of shaping stands which form the round HSS (mother tube) into the final square shape.

Uses: The product applications are mainly used to create barriers, railings, fencing, furniture, gates, street poles and vehicles parts.
