Salasar Techno Engineering Gears Up For India Thermal Boom

India is accelerating its energy infrastructure by expanding thermal capacity alongside renewable energy systems, driving unprecedented demand for advanced engineering and structural steel solutions. This industrial shift requires robust manufacturing capabilities to support large-scale power projects, turbine halls, and critical plant installations across the nation.

Heavy structural steel remains a critical element in reinforcing massive power infrastructure, ranging from complex boiler setups to comprehensive factory facilities. Firms offering unified design, production, and implementation services are strategically equipped to fulfill evolving market demands while meeting stricter efficiency protocols. In this discussion, Bharat Agarwal, President of the Heavy Structures Division at Salasar Techno Engineering, breaks down the firm’s production infrastructure, sector trends, and the outlook for heavy structural engineering in the regional power segment.

How has Salasar positioned its manufacturing capabilities to meet the demand for boiler support structures amid India’s 97 GW thermal capacity target by 2034–35?

The federal objective to add 97 GW of thermal capacity represents one of the most substantial infrastructure mandates established in modern times.

Our strategy to operationalize a specialized heavy structural steel fabrication plant in Hapur, Uttar Pradesh, combined with incremental output upgrades at our Bhilai unit—introducing 1,000 MT of volume by the close of Q2 and another 1,000 MT by Q4—directly supports this requirement. This infrastructure handles boiler supports, turbine enclosures, coal processing plants, and related utility frameworks.

The facility runs one of the broadest galvanizing lines across Asia, anchored by a 13-meter processing bath for optimized output. Our primary differentiator is an all-inclusive corporate setup covering design, detailing, fabrication, and logistics under a single umbrella, neutralizing operational handoff friction. For modern 660 MW and 800 MW supercritical facilities, individual boiler frameworks routinely top 2,000 to 3,000 MT, making localized engineering and manufacturing alignment an operational necessity rather than a premium option.

What design changes in modern thermal plants, such as higher-efficiency supercritical units, influence your fabrication processes and material specifications?

Supercritical and ultra-supercritical generation units reach operational efficiencies between 38% and 45% depending on configuration, meaning their structural specifications are far more stringent than legacy subcritical installations. A standard 660 MW or 800 MW ultra-supercritical boiler frequently climbs past 100 meters in vertical height, necessitating framing built to withstand compounding static weights, real-time thermal expansion, tectonic shifts, and wind currents. Joining high-temperature alloy metals, particularly P91 and P92 steel classifications, presents a highly technical fabrication obstacle within the advanced thermal space. Though our primary responsibility encompasses the structural framing, our drafting and welding procedures must accommodate the shifting temperatures of pressurized assemblies without transferring stress back to the main skeleton. We have updated our structural modeling suites—incorporating Tekla, STAAD.Pro, and ETABS—alongside our specialized welding configurations to manage these variables.

Can you detail engineering challenges in delivering structures for Adani and L&T projects, particularly tolerances for heavy lifts and seismic compliance?

Our contractual obligations for these assignments center on manufacturing and supply lines; our teams fabricate assemblies according to client-provided technical prints, placing the full onus of dimensional tolerances and structural integrity on our production floor. Post-delivery adjustments are virtually impossible; component deviations discovered during heavy rigging operations of 200 to 300 MT create compounding field installation expenses that are vastly more costly than identifying errors during manufacturing.

To guarantee seamless field installation, we execute comprehensive test assemblies of vital structural components, including primary columns, before logistics dispatch. This initial dry-fit protocol verifies alignment and connections within a regulated plant space, ensuring field installation proceeds without unexpected mechanical variances.

Regarding tectonic engineering compliance, we follow IS 7215 guidelines for fabrication variances, and our production loops fully match the stress load variables dictated by IS 1893 for Zone III and Zone IV regional Classifications. Connection layouts, structural gussets, and weld integrity are planned and reviewed with these specific environmental stresses in mind. Every critical structural joint undergoes rigorous non-destructive validation as a baseline protocol.

How do lead times and supply chain bottlenecks for high-tensile steel impact delivery schedules for projects under construction?

Throughout the regional power utility ecosystem, raw component supply is trailing aggregate market demand, creating visible strain across procurement pipelines, with structural steel distribution facing similar pressure. High-tensile steel grades required for heavy boiler framing are rarely available via spot market channels, and when multiple utility projects advance concurrently, mill manufacturing backlogs grow significantly. International geopolitical headwinds have constricted global raw material flows, raising acquisition costs and driving up delivery volatility for iron ore and metallurgical scrap imports.

Our containment strategy operates on two fronts: we secure mill allocations immediately upon engineering draft finalization—design validation is sufficient to lock in necessary volumes and alloy grades—and we sustain multi-year procurement partnerships with major steel producers to bypass open-market allocation delays. Maintaining a rolling inventory buffer of standard structural profiles offers an extra 4 to 6-week operational safety margin during volatile cycles.

What investments in plant automation or welding technology support scaling production for the 38 GW pipeline?

Our Hapur manufacturing base utilizes computer numerical control (CNC) automated beam fabrication corridors that handle milling, drilling, and layout etching, minimizing preparation windows while upgrading dimensional exactness. The core of this system is our specialized Coreimpex beam welding framework, which provides high-precision, accelerated output on massive structural pieces with a level of uniformity manual labor cannot match. Parallel to this, automated welding sub-systems are entering our production streams, delivering a measurable boost to manufacturing velocity and joint consistency. On the planning side, Tekla Structures generates direct CNC cutting profiles without manual data translation, eliminating a classic vector for clerical mistakes and production pauses. Combined, these technological updates permit manufacturing scale-ups without a linear expansion of personnel, a vital benefit given the systemic shortage of expert fabrication supervisors across the industrial sector.

How does Salasar balance thermal orders with renewable infrastructure work, given grid stability priorities?

Thermal projects and green energy infrastructure operate as complementary pillars in our broader commercial portfolio rather than competing divisions. Fossil-fuel generation continues to represent roughly 50% of the domestic power base, remaining crucial for baseload electrical network stability while renewable installations scale up, and both sectors consume massive volumes of structural steel. Our industrial catalog includes power transmission pylons, power substation framing, solar array racks, railway overhead wire infrastructure, and heavy factory framing, ensuring our manufacturing lines remain active even during specific sector slowdowns. Thermal infrastructure assignments typically yield larger scale, extended delivery timelines, and higher capital value per order, whereas renewable energy demands present rapid manufacturing turnarounds and higher unit volume. We run these operations via separate fabrication lines with distinct capacity boundaries to prevent internal resource competition.

What KPIs – such as fabrication yield, on-time delivery rates, or defect ppm – demonstrate your edge in thermal structures?

The operational metrics that our client base prioritizes center on physical dimension accuracy, initial weld acceptance rates, and seamless field assembly metrics. We track structural joint flaws through advanced ultrasonic and radiographic imaging, maintaining a zero-defect performance history. Material utilization efficiency—the net weight of shipped structural steel versus raw input steel after deducting manufacturing scrap—serves as a vital internal cost metric; at our operational scale, a mere 1% efficiency gain yields major annualized fiscal returns. For logistics delivery, our corporate benchmark requires fulfilling contracted monthly volume targets within a 5% variance margin, matching the operational schedules utilized by prime engineering, procurement, and construction contractors. Field assembly quality, specifically minimizing the need for manual alignment plates or field corrections, is logged continuously, and our capital investments in CNC automation directly target this operational variable.

How do you ensure quality certification alignment with international standards like ASME for exported components?

Salasar is advancing power transmission infrastructure assignments across Rwanda and Nepal, with a global corporate strategy centered on territories displaying clear infrastructure backlogs and commercial openings for fully integrated national engineering firms. In the heavy structures segment, our global footprint touches diverse markets, ranging from the Greater Malé Connectivity initiative in the Maldives via Afcons Infrastructure to prefabricated fulfillment centers in Fiji and industrial tool framing lines in Germany, with each destination imposing unique regulatory certifications that our compliance frameworks handle natively.

Our fabrication teams follow AWS D1.1 protocols for general structural joint integrity, which represents the primary technical standard enforced across global markets, including the Gulf region. For industrial processes and adjacent piping infrastructure, we utilize ASME Section IX guidelines for welder validation and procedural compliance. We cross-certify our welding personnel and industrial protocols across several global regulatory regimes simultaneously, allowing production teams to fulfill IS, ASME, or AWS requirements without facing certification pauses on new project rollouts. Independent third-party validation inspections are integrated directly into our standard export production timelines rather than causing separate delivery pauses.

Which segments of thermal expansion – brownfield retrofits or greenfield plants – offer the highest margins, and why?

Brownfield modifications offer higher profit margins due to their underlying engineering complexity. Our specialized assignments covering logistics gallery redirection and structural decommissioning face strict physical boundaries, demanding highly customized fabrication adjustments to integrate with legacy operational assets.

Future Outlook

As India progresses toward its target of 97 GW of thermal capacity alongside aggressive renewable goals, the heavy structural steel industry is poised for sustained expansion. Companies adopting automation, direct mill sourcing, and multi-code welding certifications are positioned to lead global and domestic infrastructure developments.
