Framing Structure

Framing Structure

Pro-Steel Framing

Is a light weight steel system which utilizes Cee and Zee steel purlins to form its structural roof frame. The steel purlins are interconnected with a series of plates, steel brackets and sleeve connectors, which are then, fasten together with nuts, bolts and screws. The entire frame is anchored securely to the ring beam, which is tied into the foundation of the building.

Structural Steel Framing

Structural steel framing, may include vertical columns and or horizontal I beams welded and plated together, purlins are then fasten to the steel rafters to complete the skelton frame. The engineer normally selects the size of I beams based on the span, load and size of the structure.

Timber Framing

Timber Framing includes a framing system which utilized timber to create the framing system for a roof.

Concrete Works and Screeding

Concrete Works and Screeding refers to the use of a light weight concrete to construct a roof. Lightweight concrete is a mixture of concrete mixed with a proteen foaming agent to significantly reduce the Psi of the concrete when it dries, thus allowing the concrete screed to be significantly lighter and reduced air tension within the concrete which allows the concrete screed to offer higher insulation values than a standard structural load.

Our corrugated metal panels are perfect for warehousing and large building structures. The Corrugated panels are made of high strength steel, its tough, practical and will fit your most basic needs.

Gauge

The thickness of the sheet metal is measured in Gauge. The lower the gauge number, the thicker the metal. 26 Gauge is the industry standard for residential use, while 24 Gauge is mainly used for commercial projects.

Paint Finish

Paint Finish

Polyester

Polyester Paint formulations: – contains corrosion properties, good surface adhesion with durability of appearance and mechanical strength. The finish is also flexibile so it does not fail if the substrate is dented or bent.

PVF

PVF Finish -has the all the benefits of polyester together with a pearlescent / metallic finish which is a custom formulated fluorocarbon solar-reflective paint system for excellent colour and gloss retention.

Metallic PVF

Kynar 500 resins provide superior weatherability for metal coatings. Kynar is a proprietary licensed formulation, containing at least 70%, by weight of the total resin, polyvinylidene fluoride (PVDF) providing the ultimate colour retention and performance.

Foil Insulation

Foil Insulation – consist of one layer of foil barrier of aluminium foil to provide thermal resistance. Reflects up to 95% of the radiant energy strikling it surface and its not Fire Rated.

Bubble – Tempshield

This is a premium brand of insulation consisting of 2 layers of Barrier Bubble air cellular material laminated between layers of aluminium foil. Reflects up to 98% of the radiant energy strikling it surface and its Fire Rated.

Aluminium Guttering

Gutter: A channel installed along the downslope perimeter of a roof to convey runoff water from the roof to drain into the downspouts. Our Aluminium gutter is rollformed onsite to any length required.

Soffit

Soffit: The finished underside of the eaves. Roofman Ltd offers 2 types of Soffit.

At Roofman, all our sheeting profiles can be produced in lengths to co-inside with transport conveniences. If longer lengths are required, our standing seam profile machine and guttering machine are mobile to allow the materials to be roll formed on site to required lengths.

Tear Off/Strip Existing Roof

Tear off: Removing an existing roof system.

Number of Dormers

Dormers are a framed window unit projecting through the sloping plane of a roof. Pop up from the main roofline, like a small house with its own walls, roof and window. Roof dormers provide light, added space, and ventilation to the topmost spaces in the house.

Roof Pitch

Pitch: Also known as “slope”, pitch is the measure of how “steep” a roof is. For example, if a roof is a 4/12 pitch, the roof rises 4 inches for every horizontal run of 12 inches. The pitch of the roof is a big factor in determining the tpye of profile that can be installed. Usually, a steeper roof (higher pitch) will last longer due to its better drainage capabilities.

Aluzinc

Aluzinc is a steel substrate coated on both sides with an aluminium-zinc alloy. The excellent corrosion resistance of Aluzinc is a result of the properties of the two metallic substances creating a barrier effect of the aluminium existing on the surface of the coating and the sacrificial protection of zinc.
