JCL Infra Private Limited is a one-stop-solution for all building requirements of varied customers. Our pre engineered steel buildings are uniquely designed and fabricated to suit your requirements. Built strictly following the international standards, these buildings consist of different components, meticulously designed to be compatible to each other. The fabrication of these components is carried out in factory under strict quality control as per detailed shop drawing. These components are transported to end user’s site with proper markings and assembled at the project site as per erection drawings. We cater to industrial, commercial and institutional requirements and provide enhanced speed in delivery and erection. We also provide flexibility in expansion and withstand severest weather conditions to deliver the best of pre-engineered solutions. These buildings are available in large multidimensional spans; lean to roof at all required heights and side claddings. They feature a structural steel framework of primary and secondary members (rigid frame, beams, purlins and grits, trusses and columns) on to which cladding and roofing components are attached. The plant is equipped with high precision CNC machines to fabricate and supply quality-replete steel buildings.

Steel is the basic material that is used in the construction of a pre engineered building. The usage of steel negates the usage of concrete and cement to a great extent thus mitigating any harmful effects associated with them.Moreover steel has a substantial amount of recycled content in it. The metal roof and wall panels used by PFPL have at least 25 % recycled content in them. They are also 100 % recyclable in the future after the building has lived its life. The other major advantages of steel is that it has lower life cycle cost as it is easier to maintain.The pre-engineered steel building system in itself offers great advantages to the customer as a more feasible, practical and efficient alternative to conventional buildings. The system has earned acceptance across the world and is gaining rapid ground in India as well. .

Some of the distinct advantages include:

Durability - weather resistant, earthquake resistant.
Value - Low initial investment, low maintenance costsli
Environment friendly - All the materials can be recycled
Flexible - Easy to expand, easy to setup and change
Faster - Reduced construction time
Aesthetics - Gives the engineer enough flexibility to create unique structures

Following are the components used by JCLIL for constructing steel buildings.

Main Frame

Rigid steel frames of the building are mainly considered as the Main Frames of PEB. PEB rigid frame comprises of tapered columns and tapered rafters (the fabricated tapered sections are referred to as built-up members). The tapered sections are fabricated using the state of art technology wherein the flanges are welded to the web. Splice plates are welded to the ends of the tapered sections. The frame is erected by bolting the splice plates of connecting sections together.

Purlins, Grits and Eave Struts

Purlins, Grits and Eave Struts are secondary structural members used to support the wall and roof panels. Purlins are used on the roof; Grits are used on the walls and Eave Struts are used at the intersection of the sidewall and the roof. Secondary members have two functions: they act as struts that help in resisting part of the longitudinal loads that are applied on the building such as wind and earthquake loads, and they provide lateral bracing to the compression flanges of the main frame members thereby increasing frame capacity.

Panels and Insulation

Panels used for sheeting purpose are generally of ribbed steel sheets used as roof and wall sheeting, roof and wall liners, partition and soft sheeting. The steel sheets are generally produced from steel coils having thickness 0.5 mm to 0.7 mm high tensile stress.

STEEL VS CONCRETE

Evluation Criteria	Peb Building	Concrete Building	Steel Advantage
Building Dimensions	Suitable for spans 20-30m. Can sustain much larger spans.	Suitable for short span buildings, 5-8m. Becomes difficult and heavy for larger spans.	12%-50% Cost saving for long span steel building
Fabrication	Members fabricated in a controlled environment. Precise fabrication.	Fabrication done on site. Requires building the reinforcement cage and shuttering work prior to pouring.	90% saving in fabrication time on site.
Delivery and Logistics	Can be delivered anywhere in the world. Can be properly sequenced.	Might have to build batch plant on site if site is secluded or huge.	Capital Investment saving.
Erection Time	Fast erection. Virtually no idle time	Slow erection and time consuming. Pouring should take place in limited amount of time. If exceeded, the concrete quality may be jeopardized. The contractor will have to wait for the previous cast to harden (14-28 days) before being able to cast another batch.	50% saving in construction time.
Industrial Applications	Can easily handle equipment such as multiple cranes within building. Sways can be controlled. Precision can be achieved during installation.	Heavy equipment usage such as cranes is limited. To solve precision problems, contractors use steel I beams and platforms in concrete buildings.	Saving on maintenance cost.
Quality	Quality of steel is guaranteed because It is a homogeneous product. Pieces are tailored according to shop drawings. Precise machinery is used for fabrication. It is fabricated under shop control. Quality is not affected by weather conditions	Many factors lead to quality deterioration Concrete is not a homogeneous product Concrete mix ingredient ratios are difficult to maintain. Quality of water used may vary. Weather conditions. Labor experience in pouring. Adequate use of vibrators. Using proper curing methods. Concrete shrinkage. High manpower count may weakan control.	Less time is spent to maintain steel quality.
Cost	Low man power count needed. Erection cost is low at site	Construction cost is high at site	–
Modulability & Scalability	Can change a section of the building or even cancel a section with controlled effort and with little effect on structure stability and functionality. Expansion is easy. Longitudinally expansion is about adding more bays and connecting the secondary members and the sheeting to the old building.	Needs a lot of planning and has usually major consequences. Might be even impossible. To expand, the contractor has to build a new structure with foundations, columns and might have to break part of the old structure in order to expand it.	Lower modification cost.
Error Modification	Easy to modify on site, even after erection. Modification can be done by cutting, welding or attaching steel pieces.	Have to break concrete if modification is necessary.	–
Consistency and Reliability	Strength is assured from design. Steel properties are stable with time.	Strength cannot be guaranteed without testing. Concrete properties may change over time and environmental conditions	–
Seismic Effect	Ductility of steel provides flexible behavior under seismic loads. Light Steel structures minimize the seismic effect on the structure. Steel is heavier than concrete but is 18 times stronger. A steel member can hold 6 times its own weight.	Poor flexibility under seismic loads. Heavy structures maximize the seismic effect on the structure. Heavy self weight. Large portion of concrete strength consumed to resist effect of its own weight.	–
Ductility	Show signs of failure when overloaded. Gives chance to fix the problem.	No warning signs. May result in disastrous collapse. Steel reinforcement is used to prevent brittle failure.	Steel building requires less costly safety measures.
