Membrane Structures - ETFE and PTFE
MEMBRANE STRUCTURES
The Spatial tensioned structures made out by Membranes, supported by cables, columns and constructive steel members. As a leading ETFE and PTFE manufacturers, Hindiustan Alcox cater one of the efficient ways in creating a emerging trend shade and roofing membrane structure with full versatility by building membrane structures in creative ways.
MEMBRANE STRUCTURE TYPES
From membrane structures manufacturers and application point of view, Its types are classified into two Broad categories:
-
Pneumatic Structures
-
Tensile Structures
PNEUMATIC STRUCTURES
These are air-supported Structures whose Structural Integrity depends upon use of internal pressurized air to aerate the pliable material envelope. In these types oftension fabric structures, the main structural support is from air. Our well experienced engineers come with the highest fabric standards and precision construction work to serve you a long lasting creature.
TENSILE MEMBRANE STRUCTURES
These are thin shell economic structures and attractively covers large distances carrying only tension, but no compression. The Material used for roofing membrane structures are generally (single–layered or double-layered) PTFE-coated fiber glass and PVC coated Polyester. Supportive Structural cables used in Tensile structures are a series of strands twisted or bound together, leading to a larger cable.

Airports
The integrated terminal buildings are designed with number of structural innovations. The key feature of airport structure is their long span roof covering with massive column spacing. The mega columns and large cantilevers make the structure unique. By using modular space frame structure supported by cantilevered columns makes the roof aesthetically good with doubly curved.
Bulk Storage Sheds
Bulk storage sheds are large span structure to accommodate tons of coals for continuous supply to the boilers.The structures are designed with modular space frame to make it cost effective compared to other conventional structures. Catwalks, ducts and other services can be accommodated within the top and bottom chords.
Space Frames
A space frame is a three-dimensional structure. The 3D behavior ensures optimum utilization of material. The quality of roofing is exceptionally good, as the deflections are almost negligible. Despite their light weight, these structures are designed to carry much heavier loads and have a huge spanning capacity. Erection time is minimal as the material is pre-fabricated from the factory.
Multi-Storey Buildings
Steel frames construction is a very popular structural form for multi storey buildings as it provides great flexibility. The structure has adequate strength and stiffness to resist the applied loads due to gravity and wind. The function of the structure in resisting vertical loads due to gravity and horizontal loads due to wind is generally considered separately.
Pre-Engineered Buildings
It offers a futuristic solution for creating durable and efficient structures in a cost-effective manner. Apart from great flexibility of designing and minimal construction time offered by PEB’s, they are also preferred for their robustness and durability. Moreover, it is possible to add a wide range of structural and non-structural components, which enhances their aesthetic appeal and also improves their usability.
Membrane Structures
Textile supported by steel combines the high flexibility of use of this one, from reticular arches to infinite space geometries, with a singular covering applied only under optimum conditions in order to avoid abrasion and corrosion due to contact with the main bearing structure. The all-season use is guaranteed by a singular system of side opening in order to obtain maximum ventilation in the hot season.
Self Supporting Roofs
A self-supporting roofing system makes it possible to erect a warehouse in one span without trusses, purlins, and rafters. The systems are mechanically sealed, which ensures better weather proofing and a hygienic and clean environment. The absence of holes, nuts, bolts, overlaps, or sealants, these structures require minimal to zero maintenance, making them highly cost-efficient.
