Leading commercial aluminium systems specialist LSF Commercial has tripled its manufacturing capacity over the past 12 months, following a sustained programme of investment in its Rainham, Essex facility.

The family-run business, which fabricates high-performance aluminium windows, doors, curtain walling and shopfronts for commercial projects nationwide, has extended its factory floor, introduced a new relay production system and installed a powder coating oven within a purpose-built extension.

Director, Onkar Toot, said the changes reflect a long-term commitment to keeping pace with rising customer demand.

“We’ve grown steadily for years, but the scale of change in the last 12 months has been something else. Tripling our output isn’t something that happens by accident. It’s the result of careful planning, a lot of hard work from the team and a genuine willingness to keep improving how we do things.”

The introduction of a relay system has reorganised how work moves through the factory, cutting processing times and removing bottlenecks between departments.

“Every stage now flows into the next,” Onkar said. “There’s no downtime waiting for the next part of the job to start. That change alone has made a huge difference to turnaround.”

The new powder coating oven, housed in an extension built specifically for the purpose, has added further capacity for finishing work in-house.

“Bringing more of the process under our own roof gives us far greater control over quality and lead times,” Onkar added. “It means when we make a promise to a customer we can keep it.”

The capacity upshift will also help with LSF’s supply of fire rated windows and doors. As a certified supplier of fire rated aluminium systems, customers can access products designed to meet demanding fire specifications across commercial developments.
