You are looking for Omega purlin at factory price, stable quality, meeting the correct technical specifications for workshop buildings, pre-engineered steel houses or light frame systems? This article fully summarizes knowledge from concept, applications, technical specifications, reference price list to selection criteria and comparison with other popular types of purlins. The content is built clearly, easy to understand to help you quickly grasp and choose the suitable product.
Omega Purlin Profile
Omega purlin (also known as Omega purlin or hat section/top-hat/batten) is a type of cold-formed steel section with a cross-section in the shape of the letter Ω (Omega). This design forms a “hat” with two flanges and a flat web, providing higher rigidity compared to some simple profiles in light structure applications.
The product is usually produced from galvanized steel sheet or black steel, common thickness from 1.0–3.0 mm. Thanks to the characteristic shape, Omega purlin distributes load evenly, has good anti-torsion and is easy to connect with panel sheets, roofing sheets or secondary frames. Viet Son Mechanical specializes in roll-forming Omega according to requirements, ensuring high accuracy, suitable for many construction specifications.
Applications of Omega Purlin
Omega purlin is widely used in constructions requiring light structure, aesthetics and fast construction:
- Roof frame system and roof purlin: Used as main or secondary purlin for workshops, warehouses, pre-engineered houses, industrial canopies.
- Wall, partition and ceiling frames: Supporting insulation panel sheets, suspended ceilings, interior partitions or secondary frame systems of civil and commercial constructions.
- Solar panel support frames: Used as rail/mounting structure thanks to good load-bearing capacity and corrosion resistance.
- Other secondary structures: Awnings, lobbies, waiting houses, parking areas, sunshade frames.
Outstanding advantages are light weight, fast installation, reducing load on the main structure and suitable for both medium to large scale constructions.
