Primary Structural Components

(a)Main Frames

(i)PHX Rigid Frame

Steel frames are made up to two columns and two sloped beams known as rafters, which support the roof of the building. This arrangement provides a stable frame upon which sheeting is placed to form a building. The PHX rigid frame has a clear span structure, characterized by tapered columns, tapered haunches and rafter beams. It is an ideal system for customers requiring economical and column free space for flexibility in their plant layout by offering a possible clear span of up to 120 meters.

(ii)PHX Continuous Beam

This system is based on the rigid frame concept with the addition of intermediate support columns which allows larger building width and economical designs. This system typically has a lower cost per square feet of space and offers an interior column spacing of 66ft or more. This system can be installed in any width or eave height and is ideal for larger production or storage units.

(iii)PHX Lean-To

This consists of a column and one sloping rafter. It is supported at the rafter end by an adjacent building and on the other end by a column. The structure has only one slope or pitch and depends on another structure for partial support. This type of frame provides an open, unobstructed interior space with peaked, single-slopes, slope and lean to roof configurations which spans to up to 30 meters.

(iv)PHX Deck Frame

The deck sheet components are provided for multi-storey buildings. This type of frame is typically designed to offer mezzanine floors and membrane roof applications and is aesthetically superior. The standard panel is used as a form (shuttering) on mezzanine floors. The deck frame can also be used as a deck panel over which concrete is poured. This type of structure also enhances the speed and economy of steel floor construction.

(b)End-Wall Posts

End-wall posts are vertical structural elements placed at the ends of the building, forming part of the end wall framing system. These posts provide support for the walls, which typically include doors, windows, and other openings, and contribute to the overall stability of the structure by helping with load support, weather and wind resistance.

(c)Rafters

We manufacture solid web and open web rafters for our PEBs. Rafters are the primary structural components of the roof system. They are horizontal or sloped beams that span across the width of the building, forming part of the main frame. The rafters support the roof covering and transfer theroof loads, such as the weight of the roof itself, wind, and other environmental forces, to the columns or side walls of the building.

Secondary Structural Components

(a)Purlins and Girts

Purlins and girts are structural components placed under the roof, wall and the perimeter of the PEB, hence serving as support to the roof sheet and wall cladding. Our Company offer two kinds (i) PHX- Zees and (ii) PHX-Cees which have a depth ranging from 165 to 300 millimetres and a thickness ranging from 1.5 to 3.15 millimetres. A purlin is a secondary member, and a cold-formed horizontal structural member located in the roof. Purlins support roof panels that are in turn supported by the primary structural framing. A girt is also secondary member. It is usually cold formed and overlaps at the outside column flange to form a continuous member.

(b)Eave Struts

Their primary function is to support the gutters along with acting as a junction of the roof and the wall cladding.

(c)Cable/ Angle/ Rod Bracing Tube

These components are designed to ensure the stability of the building against forces in the longitudinal director due to winds and earthquakes. Bracings are erected and tensioned to ensure that a building does not sway, and a proper plumb of a primary member is achieved.

(d)Open Web Joists

These are long-span, load-carrying components suitable for providing direct support of the floors and roof decks in the buildings. An open web joist is a fabricated structural member and is often used in a mezzanine structure. These types of joists are composed of top and bottom chords that are connected by a web of diagonal and vertical steel members, forming a truss like structure.

Claddings

Additional Components

(a)Fascias and Canopies

Fascias are surfaces, which are placed outside the building to improve its aesthetic look. A fascia can be in the form of a decorative trim or a panel projecting from the face of a wall. Canopy is an overhanging structure or projection of roof to provide shelter for any frame opening of the side or end wall. Our Company’s Phenix division offers fascias ranging from 1.2 meters to 1.8 meters in height and canopies ranging from 0.3 meters to 10 meters in width.

(b)Mezzanines

Mezzanines serve as intermediate floors between the main floors of the building. This type of structure usually consists of a mezzanine column, a mezzanine beam and a mezzanine joist to support the deck panel over which concrete is poured.

(c)Crane beams

Crane beams are components that support the crane gliders and facilitate the crane movement. We have experience in detailing and supplying crane beams to support more than 300 meters cranes.

pecialty Roofing Systems (interlock 360)

We manufacture a specialty roofing system which is a screw less roof. The roofing system is leakproof and has an inter-locking panel with a 360o mechanical seam. This roofing system is a fully seamed roof which is profiled and has a seamed ridge cap for enhanced weather tightness and rigidity at roof apex. This roofing system contains a high rib of 3 inches offering superior sectional properties which provides higher strength and ensures quicker drainage of water. An on-line sealant application ensures weather-tightness at the seam after installation. A movable clip allows for free expansion and contraction of the roof due to thermal effects.

Accessories

We externally procure bought out parts which are utilised in PEBs including fasteners, TUF-dome lite, sliding doors, mastic doors, walk-away doors, insulation, glazing windows, roof curbs, fixed ventilators, roof jack, turbo vents, roll-up doors and ridge vent sealants.
