Frequently Asked Questions

What is a Pre-Engineered Building (PEB)?

A PEB is a structural entity designed at a factory and assembled at the site. It uses a combination of built-up sections, hot-rolled sections, and cold-formed elements to provide a high-strength, lightweight alternative to traditional steel buildings.

How does PEB differ from Conventional Steel Buildings (CSB)?

CSB uses standard hot-rolled sections that are cut and welded at the site. PEB is 'engineered' to use steel only where needed, reducing weight by 20–30% and significantly speeding up the erection process.

What are the primary benefits of choosing PEB for industrial sheds?

The primary benefits include cost-effectiveness, faster project delivery (0–7 days mobilization), large clear spans (up to 60m+), and easy future expansion capability.

Is PEB suitable for multi-story buildings?

Yes. Modern PEB technology allows for multi-story structures (G+3 and higher) using mezzanine floors and composite deck slabs, often used in commercial offices and multi-level warehouses.

How long does a typical PEB structure last?

With proper maintenance and high-quality coatings (like Galvalume or specialized primers), a PEB structure can easily last 30 to 50 years.

How is the cost of a PEB project calculated?

Costs are generally calculated based on 'Price per Metric Tonne' (MT) for fabrication and 'Price per Square Foot' for the entire project including cladding.

Does Maxxinfra offer MT-based transparent billing?

Yes, Model 02 of our engagement offers transparent MT-based billing. This allows clients to pay exactly for the steel tonnage delivered and erected, eliminating hidden costs.

Are there hidden costs in PEB construction?

Common hidden costs in the industry include excess wastage and transportation. Maxxinfra minimizes this through ERP-tracked output and in-house detailing to ensure BOM accuracy.

What factors lead to cost variations in a quote?

Key factors include the bay spacing, wind speed requirements of the location, crane loads, and the choice of roofing/cladding material.

How much can I save on foundation costs with PEB?

Because PEB structures are lighter than RCC or CSB, you can save approximately 15–20% on foundation costs due to reduced dead loads.

Which Indian Standards (IS Codes) does Maxxinfra follow?

We strictly adhere to IS 800:2007 for steel design, IS 875 for load calculations, and IS 1893 for seismic resistance.

What is the 'Design Cycle Time' for a new project?

At Maxxinfra, our standard turnaround for GA (General Arrangement) drawings and detailing is 48 to 72 hours.

Can you accommodate EOT Cranes in PEB design?

Absolutely. We design Crane-Girders and columns to support EOT cranes ranging from 5MT to 100MT+ based on the industrial requirement.

What is 'Clear Span' and why is it important?

Clear Span is the distance between two columns. PEB allows for massive clear spans (up to 90m in some cases), providing maximum floor space for machinery and logistics.

How do you handle thermal expansion in long buildings?

We incorporate expansion joints and slotted holes in the secondary members to allow the building to breathe under varying Indian temperature conditions.

Where is Maxxinfra's fabrication facility located?

Our primary fabrication unit is in MIDC Butibori, Nagpur, which is a strategic hub for logistics across Central India.

What quality checks are performed during fabrication?

We conduct Visual Inspection, Dye Penetrant Testing (DPT), Ultrasonic Testing (UT) for welds, and DFT (Dry Film Thickness) checks for painting.

Can I request third-party inspection (TPI)?

Yes. We welcome TPI from agencies like RITES, TUV, or Bureau Veritas to ensure complete transparency in quality.

What kind of steel grades do you use?

We typically use high-tensile steel plates (ASTM A572 Grade 50 or IS 2062 E350) for primary members and cold-formed steel for secondary members.

What is the advantage of factory-controlled fabrication?

Factory fabrication ensures precision welding (Submerged Arc Welding), accurate hole punching, and superior surface treatment compared to site-work.

How long does the erection process take?

For a standard 20,000 sq. ft. shed, erection can usually be completed in 3 to 5 weeks depending on site readiness.

What is 'Mobilization Readiness'?

At Maxxinfra, we offer 0–7 days mobilization. Once the contract is signed, our crew and equipment are on-site and ready to start within a week.

Do you handle the civil foundation work as well?

We specialize in the Steel EPC (Engineering, Procurement, Construction) side. However, we coordinate closely with civil contractors or provide turnkey solutions including foundations via partners.

How do you ensure safety during high-altitude erection?

Safety is paramount. We use safety nets, lifelines, full-body harnesses, and conduct daily Toolbox Talks for all site crew.

Can a PEB structure be dismantled and relocated?

Yes. Since PEB members are bolted together, the entire structure can be dismantled with minimal damage and moved to a new location.

What is the 'Operate & Deliver' model (Model 04)?

In this model, Maxxinfra sets up a dedicated fabrication workshop at the client's greenfield site to eliminate transportation costs for massive projects.

Can you provide roofing and cladding solutions?

Yes, we provide single-skin Galvalume sheets, insulated Sandwich Panels (PUF/Rockwool), and standing seam roofing for 100% leak-proof performance.

How do you manage ventilation in large industrial sheds?

We install ridge ventilators, turbo vents, and louvers to ensure natural air circulation and a comfortable working temperature.

Do you assist with green building certifications?

Steel is 100% recyclable. We optimize designs to reduce steel consumption, which helps projects achieve LEED or IGBC green building points.

Why choose Maxxinfra over other local fabricators?

Maxxinfra provides 'Single Accountability.' We own the design, the fabrication at Butibori, and the erection. This eliminates the blame-game between different vendors.
