Rigid Frame with By-Pass Girts is a structural system where the primary rigid frames carry the main roof and wall loads, while the wall girts pass outside the columns instead of being interrupted at each column line. This by-pass arrangement allows the girts to run continuously along the building length, improving load distribution and reducing deflection. It also provides a flatter wall surface, making cladding installation easier and more uniform. This system is commonly used in pre-engineered steel buildings for better structural efficiency and improved architectural finish.

Structural Details define the specific design and connection aspects of a building’s framework, ensuring strength, stability, and safety. They include information on member sizes, joint connections, bolt and weld specifications, and load transfer mechanisms. Accurate structural detailing ensures proper fabrication and erection at site while complying with design codes. Well-prepared structural details improve construction efficiency and long-term structural performance.
Vertical Fascia is a vertical architectural and protective element installed along the edge of the roof or at the junction of the roof and wall. It covers and conceals the ends of roof sheets and purlins, providing a clean and finished appearance to the building. In addition to aesthetics, vertical fascia helps protect structural components from weather exposure. It is commonly fabricated from color-coated metal sheets to match the roof and wall panels.
Mezzanine Joist Connection to Mezzanine Beam refers to the structural connection where secondary joists are securely fixed to the primary mezzanine beams to support floor loads. These connections are typically made using bolted or welded end plates, angles, or seat connections to ensure proper load transfer. A well-designed connection provides stability, minimizes deflection, and ensures safety under live and dead loads. Proper detailing also allows for efficient fabrication, erection, and long-term performance of the mezzanine structure.
Canopy is a projecting roof or cover attached to a building, designed to provide shelter and protection from sun, rain, and weather. It is usually supported by brackets, columns, or tie rods and constructed using steel frames with roof sheets. Canopies enhance functionality by covering entrances, walkways, loading areas, or parking zones. In addition to protection, they also add to the architectural appeal of the building.
Parapet Fascia is a vertical or slightly inclined finishing element installed along the top edge of a parapet wall. It serves both decorative and protective functions, concealing the roof edge and preventing water ingress into the building structure. Typically made from color-coated metal sheets, the parapet fascia enhances the building’s appearance while safeguarding structural components from weather exposure. It is commonly used in industrial, commercial, and pre-engineered buildings.
Mezzanine Beam Connection to Main Frame Column refers to the structural joint where the primary mezzanine beams are securely attached to the main building columns. This connection ensures that the mezzanine floor loads—both live and dead—are effectively transferred to the main frame. Connections can be made using bolted end plates, welded joints, or bracket supports, designed to provide stability, minimize deflection, and maintain the overall integrity of the structure. Proper detailing is essential for safe erection, load distribution, and long-term performance of the mezzanine system.
Roof System with Insulation is a roofing setup that combines structural roof panels with thermal insulation layers to improve energy efficiency and indoor comfort. The insulation can be in the form of rigid panels, blankets, or spray foam, and is installed between the roof sheet and the structural framing. This system helps regulate building temperature, reduces heat transfer, and prevents condensation inside the building. It is commonly used in industrial, commercial, and pre-engineered buildings to enhance thermal performance and reduce energy costs.
Endwall Roof Extension with Soffit is a structural and architectural feature where the roof extends beyond the endwall of a building, and a soffit is installed beneath the overhang. The roof extension provides additional protection against rain, sun, and wind at the building’s end, while the soffit offers a finished appearance and helps with ventilation. Typically made of metal sheets, the soffit conceals structural members and enhances both aesthetics and functionality of the roof overhang.
Sidewall Roof Extension is a design feature where the roof extends beyond the sidewalls of a building to provide additional protection from sun, rain, or snow. This extension shields the walls, doors, and windows, reducing weather exposure and improving the building’s durability. Sidewall roof extensions can also create covered walkways or loading areas and are typically made using the same roofing materials as the main structure. They enhance both the functionality and the aesthetic appeal of the building.
LIGHT GAUGE FRAMING SYSTEM
Light Gauge Framing System is a new concept which deals with effective budgeting and following of techniques which help in reducing the cost construction through the use of locally available materials along with improved skills and technology without sacrificing the strength, performance and life of the structure. There is huge misconception that low cost housing is suitable for only sub standard works and they are constructed by utilizing cheap building materials of low quality. The fact is that Low cost housing is done by proper management of resources. Economy is also achieved by postponing finishing works or implementing them in phases. Now in low cost housing, building material cost is less because we make use of the locally available materials and also the labour cost can be reduced by properly making the time schedule of our work. Cost of reduction is achieved by selection of more efficient material or by an improved design.

TURBO VENTILATOR :
Turbo Vents are rotary devices to pull out warm and stale air in warm months and moist air in cold months. They are commonly located on roof tops, using only wind and pressure diff erences as their power source. They offer energy savings and comfort with low up-front cost
RIDGE VENTILATOR :
Engineered ventilation system using continuous ridge ventilators will control the movement of fresh air through the building removing hot, stale air and air contaminated by manufacturing or production processes.
SELF TAPPING SCREWS :
A self-tapping screw is a screw that can tap its own hole as it is driven into the material. For hard substrates such as metal, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap
SKYLIGHT :
Skylights are light transmitting fenestration (elements filling building envelope openings) forming all, or a portion of, the roof of a building’s space for daylighting purposes
DECK SHEET :
Composite Floor Deck is a steel deck with a ribbed profile, which binds with concrete slab and together forms a part of the floor structure. This interlocking between the concrete and the floor deck is brought about through a system of embossment and ribs which are built into the deck, creating a reinforced concrete slab that serves the dual purpose of permanent form and positive reinforcement. Composite decking is one of the most effective method of constructing floors in steel building and very useful in high rise RCC / Steel Buildings.
BENEFITS OF METAL DECK SHEET
• Light weight and doesn’t require any support, which considerably reduces the use of concrete & slab thickness.
• Acts as composite member and as permanent shuttering.
• No major reinforcement required.
• Deck can be used as working platform during construction.
• Speedy construction enables faster completion of a project.
• Metal deck can also be used as roofing and cladding sheet in cement, power plants and bulk material handling plants.
• Decking reduces the construction time, hence the total cost.
