Pre-Engineered Building

Primary Main Frames
Pre-engineered buildings offer complete freedom of design to accommodate customers need. DEMCC has particularly developed several types to offer optimized economical configuration for customers to choose from according to space, span, crane and architectural requirements.

Clear span Frame
When building width is less than 25m, clear span frame will provide
un-interrupted clear workspace in the building. When building width is more than 25m, it will not be an economical choice to the customer.

Airport Hangers
The width of the buildings may vary from 30m to 110m depending upon the number and type of aircraft. Hangers up to 60m clear span are economically built using pre-engineering building system; however, for span exceeding 60m, a structural truss-column system becomes more economical

Multispan Frame
The introduction of interior columns allows for grater spans without internal gutters and rainwater pipes. This type of design optimizes bay spacing, building weight and therefore cost

Single Slope buildings are offered with single or multi-span modular options. Straight or tapered columns are available.

Multi Gable Buildings are maintaining a low ridge height for very wide buildings.

Curved Roof gives a special appearance to the building and modular width also can be increased.

Roof System
When Concrete wall exists to support main building, utilizing the support, the roof system will be the cost-effective solution and more workspace to the client can be achieved. However, there will be a limitation on building span.

Lean-to and Car Canopies
These building enhancements are ideal for car parking, building expansions. The structure can be made of hot-rolled or built-up sections. Lean-to’s require a supporting structure to take the lean-to reaction.

Secondary end wall Frame
Simple end wall frame with pin connected rafter and columns will reduce the building weight and on cost. However, if the future expansion of the building is expected along the sidewall, Rigid frame should be used at ends. The standard end wall column spacing would be 6 mts. Endwall column and rafter can be made from hot-rolled, built-up or cold form cee. Flush girt is a standard feature for end wall framing.

Cold form structure
Supporting members for wall and roof panels are girt and purlin. Cold form Zee section is used as purlin and girt. Standard height of Zee and Cee sections are 202mm. However, DEMCC can supply any depth of Zee and Cee sections ranging from 125mm to 300mm. Cee sections are widely used as frame open members; jamb, header, and sills. Also, Cee section is used as end wall column and rafter. Main advantage on cold form members are
1. As raw material is pre-galvanized, no painting is required and self rust proofing.
2. There is no welding involved in the members and production is automated, hence accurate and faster supply of final product is assured.
3. Member weight is relatively less, so handling will be very much eased.

Secondary end wall Frame
Rod and angle shapes are used as bracing members in wall and roof bracing system. End wall framing system carries wind load and transfers them through strut purlin and then bracings to the ground. Standard brace rods are rod dia 16, 20, 25 and 32mm
