The system is suitable for steel structure warehouses, factories, workshops, logistics centers, agricultural buildings, commercial facilities and large-span industrial buildings.

Roof panels can be supplied together with ridge caps, flashing, gutters, skylight systems, insulation materials and fastening accessories to form a complete roofing solution.

Key Features

High Strength & Durability

Profiled steel roof panels provide excellent rigidity and structural performance while maintaining a relatively lightweight construction.

They are suitable for large industrial buildings where roof systems need to withstand wind loads, rain, snow and long-term environmental exposure.

Excellent Waterproof Performance

The roofing system uses properly designed panel overlaps, flashing, ridge caps, sealing materials and fasteners to reduce the risk of water penetration.

Standing seam systems can also be provided for projects requiring enhanced waterproofing performance.

Corrosion Resistance

Roofing sheets can be produced with:

• Hot-dip galvanized coating

• Galvalume coating

• Pre-painted steel coating

• PVDF coating

• Polyester coating

• Other protective coatings

Different coating systems can be selected according to climate conditions and project service life requirements.

Fast Installation

Large prefabricated roofing sheets significantly reduce on-site installation time.

Panels can be manufactured according to building dimensions, helping minimize cutting, material waste and installation labor.

Thermal Insulation Options

For buildings requiring improved thermal performance, the roof system can be combined with:

• Rock wool insulation

• Glass wool insulation

• PU insulation

• PIR insulation

• EPS insulation

• Insulation blankets

This helps improve indoor temperature control and building energy efficiency.

Customizable Design

Roof panel dimensions, profiles, colors, thicknesses, coatings and accessories can be customized according to:

• Architectural drawings

• Structural drawings

• Local climate

• Building function

• Insulation requirements

• Wind and snow load conditions

Technical Parameters

Roof Panel System Types

1. Corrugated Steel Roof Panels

Profiled steel sheets are one of the most widely used roofing solutions for industrial steel buildings.

They offer:

• High structural rigidity

• Lightweight construction

• Fast installation

• Economical project cost

• Multiple profile options

Suitable for warehouses, workshops, factories and agricultural buildings.

2. Standing Seam Roof System

Standing seam roofing uses concealed mechanical connections between adjacent panels.

Main advantages include:

• Excellent waterproof performance

• Fewer exposed fasteners

• Clean architectural appearance

• Good thermal expansion capability

• Suitable for large-span roofs

It is commonly used for large industrial facilities, airports, exhibition centers and logistics buildings.

3. Insulated Roof Panel System

Insulated roofing systems combine steel sheets with thermal insulation materials.

Available insulation materials include rock wool, glass wool, PIR, PU and EPS.

This solution provides improved:

• Thermal insulation

• Acoustic performance

• Fire protection

• Indoor comfort

• Energy efficiency

4. Sandwich Roof Panels

Sandwich panels consist of external metal sheets and an insulation core.

They are widely used for:

• Industrial workshops

• Warehouses

• Cold storage buildings

• Food processing facilities

• Commercial buildings

Roof System Components

A complete industrial roof system may include:

Roof Panels

Main waterproof and protective surface of the building.

Ridge Cap

Installed at roof ridges to prevent water penetration and protect panel joints.

Roof Flashing

Used around roof edges, wall junctions, skylights and penetrations.

Gutters

Collect rainwater from the roof and direct it into the drainage system.

Downpipes

Carry rainwater safely from gutters to ground drainage systems.

Skylight Panels

Translucent roofing panels can introduce natural daylight into warehouses and factories.

Roof Ventilation System

Roof ventilators, ridge ventilation and natural ventilation openings can improve airflow inside industrial buildings.

Fasteners & Sealing Materials

Self-drilling screws, clips, washers and sealants ensure reliable panel connections and waterproof performance.

Insulation Options

Depending on local climate and building function, different insulation systems can be selected.
