Therefore, the erection will be done efficiently the schedule due to the erection procedure of the steel structure building fabricator company.

Maintenance Work

Due to poorer erection of the steel structure buildings specifically in the part of roof sheeting leakage will happen. Then, our company has the ability to avoid the leakage and other problems by skilled erectors those who has specifically trained to maintain the particular problem.

Therefore, our company has to maintain for any parts of the steel structure buildings due to customer requests.

Foundation Work

Our company has to innovate the construction of foundation a work which is used only to the purpose of pre-engineered and structural steel buildings.

Any building, regardless of size type, depends on a good foundation for a satisfactory life expectancy and a minimum maintenance last during that life. Accurate foundation dimensions and proper anchor bolt locations and critical to the overall erection procedure. Therefore, it should be accurate and within the tolerance specified in the erection drawing out company has to innovate the construction of foundation work which is used for any purposes including pre-engineered and structural steel buildings.

Products:-

A. PRE ENGINEERED STEEL BUILDING :-

Pre-engineered buildings are defined by the following geometrical parameters: Building width, Length, Eave height, Roof slope, Sidewall bay spacing, end wall bay spacing and main frame module space. Also design loads are the basic parameter. Building Length and width are defined by the distance between steel lines. Extreme surface edges of girts and purlins are treated as steel line. Sum of side wall bay spaces will be equal to the building length. Eave height is the distance from Finished floor level to inter section point of roof and sidewall steel line. Roof Slope is defined as the ratio between vertical distance and horizontal distance of the roof surface. Standard roof slopes are 0.5:10 and 1.0:10 To describe the side wall bay spacing, main frame column spacing to be referred start from back end wall steel line to right end wall steel line. Same way back end wall and front end wall bay spacing to be given from left side wall steel line to right side wall steel line.

Primary Main frames: Pre-engineered buildings offer complete freedom of design to accommodate customers need. EBS has particularly developed several types to offer optimized economical configuration for customers to choose from according to space, span, crane and architectural requirements.When building width is less than 25m, clear span frame will provide un-interrupted clear work space 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 90m 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.

Multi span Frame:-The introduction of interior columns allows for greater 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 special appearance to the building and modular width also can be increased.

Roof system:- When Concrete wall exist to support main building, utilizing the support, roof system will be the cost effective solution and more work space 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.

High rise and Low rise Buildings

High and Low rise buildings are usually city block commercial developments. The architectural and aesthetic requirements will control interior and exterior column spacing and therefore grid (bay) size.

Building framing consists of either two way rigid frame, in a one-way rigid and one-way braced frame or Two way braced frame. The floor deck consists in either:

- a low depth non-composite profiled steel deck supported by joints, beams
  and intermediate support column, or

- a composite profiled steel deck supported as above, or

- a pre-cast concrete plank, whether hollow core, solid or pre-slab resting on
   the joists / beams.

The beams will be typically fitted with stubs to ensure composite action along their axis.

Multi-storey structures can be sub-divided into:

1. Fully steel framed structures with rigid frame or braced frame systems
2. Beam and column steel frames connected to reinforced concrete core or
    shear wall.

Commercial Building: Low rise building.                   Office Tower Bahrain
No of Floors : B + G + 4 + P                                   A high rise building.

Building Size : 34.6m x 40.2m                                  No of floors : 19+4 floors Height : 90m,Size : 23mx31m    

Steel Deck Slab
The floor system consists of concrete supported on steel decking sheet which is resting on composite or non-composite joist and beams. For composite joist and beams shear stud connectors can be field welded through decking or shop welded with decking pre- punched. The steel beams have the flexibility to allow penetrations within the web depth to allow services to pass through by providing web openings.
