Commercial & Public Building Retrofit

Prefabricated wall and floor systems that cut site time, not standards.

LJXincai supplies SPC wall panels, SPC stone-crystal flooring and bamboo-wood fibre wall panels for schools, hospitals, hotels and office retrofit projects — installed dry, over existing substrates, with project-level technical support.

Two systems, five products

One supplier for wall and floor finishes

Everything is specified as a system — panel, edge detail, fixing method and accessory — so the finish performs as one assembly instead of five unrelated products.

System 01

SPC Wall Panel System

Rigid stone-plastic composite panels with a decorative surface, for corridors, wards, classrooms and hotel guest rooms. Suitable for direct application over sound existing substrates.

System 02

Bamboo-Wood Fibre Wall Panel System

Wood-grain textured panels and impact-resistant panels for high-traffic interiors — school corridors, hospital public areas, hotel public zones and office fit-out.

Why projects choose this route

Built around the constraints of occupied buildings

Most of our work is retrofit: the building is in use, the schedule is fixed by a school holiday or a hospital that cannot close a ward. The system is designed for that reality.

Dry installation

No wet trades, no plaster, no curing time. Panels are cut and fixed on site, so a floor can be handed back the same week it starts.

Time-window fit

Scope can be split into night shifts, weekend windows or vacation periods — the installation sequence is planned around the operating schedule.

Substrate tolerance

Works over existing renders, tiles and board without full demolition, which reduces waste removal and structural intervention.

Consistent batch colour

Decorative films are controlled by batch, with physical samples issued before production so approved colours match on site.

Project technical support

Shop drawings, detail nodes, quantity take-off and installation guidance are provided with the material package.

Documented performance

Fire class, environmental declarations and test reports are issued per product so the specifier has paperwork to submit.

Verification, stated plainly

What is verified — and what is still in progress

  • Environmental Product Declaration (EPD) and Product Carbon Footprint (PCF) verification completed for two wall-panel products by an independent verification body; the statement carries a qualified conclusion with limited assurance.
  • Fire performance of panel products is Class B1 per GB 8624. Test reports are available for project submission.
  • Two invention patent applications covering the fixing node and the coating process are under substantive examination; no patent rights have been granted.
  • Green building material product certification is in application.
  • Production is carried out by our contract manufacturing partner, Chengdu Jinhaiba New Building Materials Co., Ltd., an independent legal entity holding ISO 9001 / 14001 / 45001 certification.

“We quote the limitation before the client asks for it. A verification statement with a qualified conclusion is still useful — but it is not a certificate, and we do not present it as one.”
