PRE-ENGINEERED BUILDING:

D2J Engineering’s Technological improvements over the years have contributed immensely to the enhancement of quality of life through various new products & services. One such revolution is the Pre – Engineered Buildings. Its origin can be traced back to the last four decades; its potential has been felt only during recent years. This was mainly due to the development in technology, which helped in computerizing the design.

A recent survey by the Metal Building Manufacturers Association (MBMA) shows that about 60% of non-residential low-rise buildings in the USA are PEB’s.

PEB are steel structures built over a structural concept of primary members, secondary members, roof & wall sheeting connected to each other & various other building components. The building can be provided with skylight, wall lights, turbo vents, ridge ventilators, roof monitors, doors & windows trusses, mezzanine floors, fascias, canopies, crane systems, insulators, etc., based on customers’ requirements. These buildings are custom designed to be lighter in weight & high in strength. It is also economical in cost, factory controlled quality, durability, longevity, flexibility in expansion, environment-friendly, faster installation, etc.

SELECT FROM SPECTRUM OF COLOURS

CRIMP CURVE

D2J Curved Profile – D2J Hi Rib Profiles are available in concave and convex curved sheets to give architectural aesthetic to the building. The minimum recommended radius is 500mm.

DECK SYSTEMS

D2J Deck can be used as a composite floor system or as a permanent form work. The fast and simple installation of this high strength platform gives immediate access to a walking platform. It’s saves considerable construction time which in turn saves overall cost, provide safety and accessibility of the project.

D2J Deck is cold formed in 44mm depth, 130mm pitch, cover width of 910mm and overall width of 960mm out of galvanized and HR Coils in the thickness of 0.80mm to 2.5mm.

Used in composite design, D2J Decking System performs as a positive reinforcement and a permanent form support providing saving in concrete and reinforcement.

ADVANTAGES

Lower weight reduces foundation requirement.
Highly recycled and can be continued to be recycled continuously.
Durable if protected from corrosion.
These are Pre-Fabricated sheds and have 100% salvage value at any time.
It can be relocated to other location.
No welding at site is required. It is very safe for industries were welding inside plant is restricted.
The construction time is very less in comparison to civil work.
Self-supporting readymade components are used, so the need for shuttering and scaffolding is greatly reduced.
Construction time is reduced and buildings are completed sooner, allowing an earlier return of the capital invested.
On-site construction is minimized.
Quality can be controlled while the product is in production.
Less waste is generated.
Molds can be used several times.
