Shenzhen Somei Building Material Co., Ltd. provides integrated roof solutions for steel structure factories, warehouses, cold rooms, and logistics buildings in hot-climate markets. By combining photovoltaic roof panels with PU and rock wool insulated roof panels, we help project owners reduce energy consumption, improve indoor comfort, and extend roof service life.
Photovoltaic roof panels integrate solar power generation, waterproof roofing, and thermal insulation in one system. Installed directly on steel purlins, they are ideal for new-build steel structures and large roof renovation projects.
Key advantages:
Generate clean electricity while providing a high-performance roof
Reduce structural weight compared with concrete roofs and PV racks
Fewer roof penetrations and lower risk of water leakage
Suitable for large-span warehouses, factories, and logistics centres
PU insulated roof panels are widely used on steel structure workshops, warehouses, and carports. With high thermal insulation and light weight, they are a cost-effective solution for most industrial roofs.
Benefits for your project:
Better indoor temperature control and lower cooling energy
Fast installation with factory-cut panels and self-drilling screws
Durable coated steel or aluminum skins for harsh environments
Different thickness and profiles to match local climate and span requirements
For projects where fire safety is a key requirement, rock wool roof panels offer non-combustible cores and stable performance.
Suitable for:
Chemical and pharmaceutical plants
Public buildings and high-occupancy facilities
Warehouses storing flammable or high-value goods
Rock wool panels provide reliable fire resistance while still offering good thermal and acoustic performance.
In many projects, the best result comes from a combination of systems:
Photovoltaic roof panels on main roof areas facing the sun
PU insulated roof panels on standard industrial roofs
Rock wool roof panels in fire-critical zones
Somei works with a network of qualified panel producers to select suitable specifications for each zone, based on climate, building function, fire code, and project budget.
If you are planning a new steel structure factory or warehouse, or upgrading an existing metal roof, our team can review your drawings and propose a practical roof solution using photovoltaic and insulated roof panels.
