Product Description
PIR Color Steel Plate, a remarkable composite, consists of a sturdy steel outer layer and a PIR foam core. The high - quality steel, either cold - rolled or galvanized, is pre - painted to resist corrosion and offer aesthetic options. The PIR foam, formed by polyols and isocyanates, has a closed - cell structure, ensuring top - notch thermal insulation. With thicknesses of the steel sheet ranging from 0.3mm - 0.8mm and PIR core from 50mm - 200mm, it caters to diverse construction needs.
Application
Residential Buildings
Roofing Protection: In suburban single - family homes, PU color steel roofing offers excellent protection against the elements. The waterproof steel surface and insulating PU foam keep the interior dry and warm.
Exterior Wall Insulation: As exterior wall cladding, it adds an extra layer of insulation. This reduces the need for excessive heating in winter and cooling in summer, resulting in a more comfortable living environment and lower energy bills for homeowners.
Construction Ease: The light weight of the PU color steel plates simplifies the construction process. This makes them an attractive option for both new home construction and renovations.
Cold Storage Facilities
Thermal Insulation: The low thermal conductivity of the PU foam core makes it ideal for maintaining low temperatures. In large - scale cold storage warehouses for perishable goods, PU color steel plates are used on all sides of the storage area.
Heat Infiltration Prevention: Tightly sealed joints between the plates prevent heat infiltration. This ensures the cold temperature inside the warehouse is well - preserved, reducing energy consumption for refrigeration and extending the shelf life of stored products.
Durability in Harsh Conditions: The durability of the steel layer withstands the harsh conditions inside cold storage, such as condensation and temperature variations.
Composition
Temporary Structures
Easy Assembly: The easy - to - install nature of PU color steel plates allows for quick assembly. Construction site offices can be rapidly erected using pre - fabricated PU color steel panels.
Lightweight and Portable: The panels are lightweight, making them easy to transport to the site. This is convenient for temporary structures that may need to be relocated.
Comfort and Aesthetics: The thermal insulation properties keep the interior of temporary structures comfortable in different weather conditions. In event pavilions, the aesthetic appearance of the plates can be customized to match the event theme, and in emergency shelters, their fire - resistant and durable nature provides a safe space.

Advantages
Excellent Fire Resistance
PU color steel plate has good fire resistance performance. Although polyurethane itself is flammable, through special treatment and the addition of fire - retardant agents, the PU core in the color steel plate can meet certain fire - protection standards. The steel outer layer also acts as a physical barrier, preventing the spread of fire and heat. In case of a fire, the PU color steel plate can delay the spread of flames, giving people more time to evacuate and firefighters more time to carry out rescue work. This makes it a safe choice for buildings where fire safety is a top priority, such as hospitals, schools, and public buildings.
Superior Waterproof and Moisture - Proof
Thanks to its seamless construction and the hydrophobic nature of the materials, PU color steel plate is highly waterproof and moisture - proof. The closed - cell structure of the polyurethane core does not absorb water, and the steel surface is also resistant to water penetration. This property is especially important in areas with high humidity or frequent rainfall. In buildings like bathrooms, kitchens, or industrial plants dealing with water - related processes, PU color steel plate can prevent water leakage, mold growth, and corrosion, thus extending the service life of the building and maintaining a dry and healthy indoor environment.
Easy Installation and Fast Construction
Installing PU color steel plate is relatively easy and can significantly speed up the construction process. The pre - fabricated panels come in standard sizes and can be quickly assembled on - site. The lightweight nature of the product makes it easier to handle and position accurately. Additionally, the simple connection methods, such as interlocking joints or screws, require less skilled labor compared to traditional building materials. This not only reduces the overall construction time but also minimizes construction - related disruptions. Whether it's a small - scale renovation project or a large - scale new construction, PU color steel plate can help complete the work more efficiently, saving both time and money.
