  • At Ahura, we also offer cabins with multiple joints (waterproof joints) to clients where a single unit may not be the ideal option. These multiple units are joined in a way that no column is seen in-between the open space of the portacabin. We have pioneered especially in these units to such an extent that 10% of our bookings are these big project offices.
  • G+1 & G+2 options are also available should you have space constraint. Such units are more practical in areas within factory workshops / premices.
  • Our customers are free to customize any design by adding or removing half / full partitions, toilets, pantry units, manager units, conference rooms, waiting area, accommodation etc.
  • All portacabins have an advanced “LIFT N SHIFT” type design which can be relocated within no time.
FLOOR
  • 6” or 5” C channels as base at every 4’ with 2” ISMA interwelded at every 2’ making it the strongest & most rigid base in its class (2’ x 2’ grid work).
  • In certain units we provide skid mounted cabins where there are 2 nos. 8” runner beams that are 2 mtrs apart & connected by means of channels. 3” base ISMC over the 8” beams at every 2’ & 2” angles again interconnected at 2’ (again 2’ x 2’ grid work but skid mounted)
  • 18mm / 20mm asbestos free duraboard on top of the grid structure for an unmatched superior base.
  • 1.65mm homogenous anti-scratch & anti-skid PVC carpet with wooden finish as final finished flooring.
WALLS
  • We provide several options as outer wall skin viz 16SWG flush / corrugated GI sheets or 18SWG flush / corrugated GI sheets. Toilets are strictly clad with 4mm ACP panels for prevention from acidic reaction. Optionally customers may also choose from FRP sheets, PPGI sheets, cement sheets, cement wall planks, decorative all aluminum grill sheets, WPC panels etc.
  • The internal framework of the cabin is altered & designed as per the size of the cabin & loadbearing data in case of specialized portacabins. However it typically is made from hollow tube sections that are 100mm / 80mm / 40mm in load bearing ht & ~3mm to 4mm in thickness.
  • Most of our office units have 6 mm 100% waterproof pre-laminated PVC sheets with air-gap on the inside. Optionally clients may also opt for 9mm pre-laminated MDF boards / cement wall cladding panels / planks, ACP panels (recommended in panel rooms), GI sheets and aluminum sheets (recommended in kitchens) so on & so forth.
  • Cavity in between the inner & outer skins shall be filled with special high density thick insulation so as to avoid overheating of the cabin (Density range = 22kg/m3 to 100kg/m3). However, most of our cabins have 50mm thick RB slabs from Rockwool as insulation. The density of these slabs is 45kg/m3 and these are fire safe. Download the brochure from the download section to understand more about the thermal & sound insulation of these slabs.
  • Internal partitions may be provided wherever required & have the same specs.
ROOF
  • The roof top is a self draining type design having thick 16 SWG / 18SWG GI sheets. Each sheet will have overlap on all sides and sheet will be fully welded using CO2 welding to prevent ingress of water. Moreover there shall be HMPS hat sections provided at each sheet joint so as to guide the water from the roof rather than preventing seepage.
  • We also have an optional “Hot Air Roof Extraction” system where the roof profile protrudes out of the side walls by an additional 9” (only along the length). This system has two or more exhaust fans sucking out hot air from the roof frame void. Thus fresh air is drawn in from one end & hot air from within the roof void is thrown out at the other hence reducing the temperature within the cabin during extreme heat conditions. Even in this type of roof frame, insulation is provided.
  • Additionally hollow tube frame to support the side GI flush sheets. The corss section of the tubes depends on the size & loadbearing calculation of the portacabin frame.
  • Like in the side walls, there is a variety of interior cladding options for the roof, the most common one being 4mm bakelite sheets. Our customers are also free to choose from ACP panels, 2’x2’ grid type ceilings, cement planks, decorative sheets, wooden planks etc.
  • Cavity in between the inner & outer skins shall be filled with special high density thick insulation so as to avoid overheating of the cabin (Density range = 22kg/m3 to 100kg/m3). However, most of our cabins have 50mm thick RB slabs from Rockwool as insulation. The density of these slabs is 45kg/m3 and these are fire safe. Download the brochure from the download section to understand more about the thermal & sound insulation of these slabs.

    2. The entire outer sheet flush surface is so welded that there is no application of putty on the outside preventing peel off with the passage of time. The entire surface is pure paint only.
    3. 18SWG GI flats at sheet joints are stuck to the outer shell creating a life-long ~40% elastic joint (PU sealants from 3M)
