Full Plants, Fuller Order Books: Why Steel Strips Wheels Ltd (SSWL) Is Racing to Add Capacity

For a company that built its reputation stamping steel wheels for Maruti hatchbacks and Ashok Leyland trucks, Steel Strips Wheels Ltd. (SSWL) is increasingly telling an aluminium story.

The company's July 2026 investor presentation and conference call with analysts, during its first-quarter FY27 results, sketch out the most aggressive capacity build-out in its 35-year history, and one that tilts decisively toward the lighter, pricier end of the wheel market. SSWL is adding 1.2 million units of alloy wheel capacity at its Bhuj, Gujarat, facility, taking total alloy capacity from 5 million to roughly 6.2 million wheels by the end of FY27. Alongside sits an expansion of its newest product line, aluminium steering knuckles, the forged component that connects a car's wheel assembly to its suspension, with capacity slated to more than double from 0.5 million to 1.1 million units.

The steel side of the house is not standing still either. SSWL is building a 2-million-unit brownfield steel wheel expansion near Chandigarh, an addition to an existing site rather than a greenfield project, which management expects to commission before the end of calendar 2026. That would lift steel wheel capacity from the current 20.7 million units, where the company says demand from passenger vehicles and the farm sector has left little slack.

The numbers behind the urgency are straightforward. Management told analysts that existing facilities are running at over 95% utilisation, with the knuckle line effectively sold out at 100%. When a plant runs that hot, every incremental order either waits or walks. Capacity, in other words, has become the binding constraint on growth.

The quarter that made the case

Q1 FY27 gave management a strong platform from which to sell the expansion. Standalone revenue rose 27.2% year-on-year to Rs 1,510 crore, EBITDA climbed 33% to Rs 162 crore, and profit after tax jumped 43.3% to Rs 71.5 crore. Wheel volumes grew a more modest 7.9% to 52 lakh units, which means the real work was done by mix and pricing, not tonnage.

That gap between volume growth and revenue growth is the premiumisation story in miniature. Alloy wheels, the cast aluminium wheels that carmakers fit on SUVs and higher trim levels because they are lighter and look better, contributed 35% of Q1 revenue. Steel wheels, the commodity workhorse, delivered 63% of revenue.

The clearest single measure of the shift is a metric the company itself tracks: EBITDA per wheel, essentially the operating profit earned on each wheel shipped. That figure hit a record Rs 314 in Q1 FY27, up from Rs 262 a year earlier and ahead of management's own guidance of around Rs 300. Richer alloy mix, operating leverage and successful price revisions with OEM customers all contributed, and management expects the number to keep drifting upward.

There is also a quieter structural change protecting those margins. SSWL has moved from quarterly to monthly aluminium price settlements with its OEM customers, meaning raw material cost swings now pass through to vehicle makers within weeks rather than over a full quarter. In a business where aluminium is the single largest input for the growth engine, that materially de-risks the P&L from commodity volatility.

Exports: from drag to tailwind

If aluminium is the growth engine, exports are the recovering patient. SSWL's overseas business, spanning customers from Renault in Romania to buyers across the US, Latin America and Southeast Asia, had a weak FY26 as tariff-related disruptions crimped shipments. Q1 FY27 export revenue of Rs 127 crore was still down about 21% year-on-year.

But the direction of travel has changed. Export revenue rose 37% quarter-on-quarter, and June 2026 recorded the first year-on-year export growth in nearly two years. Management is holding its FY27 export revenue guidance at roughly Rs 600 crore, an ambitious ramp-up from the Q1 run rate, anchored in newly secured OEM programmes across Europe, Latin America and Asia that deliberately reduce dependence on the US market. A technical alliance with ARS China is meant to bolster the company's aftermarket presence and technology capability abroad.

For an Indian auto components sector still recalibrating around shifting trade policy, SSWL's playbook of diversifying the customer map, leaning on aftermarket channels, and partnering for technology is becoming a familiar template.

Demand at home does the heavy lifting

The domestic backdrop remains the foundation. SSWL claims a 39% share of India's passenger vehicle steel wheel market, 53% in medium and heavy trucks, and 43% in tractors, with deep relationships across Maruti Suzuki, Hyundai, Mahindra, Tata Motors and Ashok Leyland. On the alloy side, its share of business runs as high as 74% with Hyundai and 64% with Mahindra, riding models such as the Creta, Thar Roxx and XUV700 — precisely the SUV-heavy end of the market where alloy penetration keeps rising.

The industry math favours the pivot: the steel wheel market is expected to grow about 4% a year over the next five years, versus roughly 12% for alloy wheels. Every EV launch strengthens the trend, since lighter wheels and knuckles help offset battery weight. Lower "unsprung" weight (the mass not carried by the suspension) improves both range and ride.

Management has reiterated FY27 revenue guidance of Rs 6,500 crore, implying growth of above 20%, with the knuckle business expected to nearly double its revenue within the year. The Bhuj capacity, the company says, is substantially pre-committed through customer programmes, with trial production targeted for Q4 FY27.

The watch-list

The balance sheet, for now, is carrying the ambition comfortably. The risks are the usual ones for a capex-heavy auto supplier: a soft patch in domestic vehicle demand, sharp raw material swings that outrun even monthly pass-throughs, or, most pertinently, delays in ramping up the new alloy and knuckle lines, which would push out the earnings the expansion is meant to deliver. The export guidance also assumes a steep second-half acceleration from a modest Q1 base.

For now, though, the sequencing looks deliberate: fill existing plants first, pre-sell the new capacity, shift the mix toward aluminium, and let the export recovery arrive as upside rather than a prerequisite. It is a wheel maker's version of not reinventing the wheel, but instead just casting it in a lighter metal.
