Ningbo Fengyi New Materials Co., Ltd.

Waterproof, Weather & Corrosion Resistant Pre-Coated Panels for Construction

Large red pre-coated color steel sheets adopt composite production technology with high-weather-resistant polyester topcoats applied on hot-dip galvanized substrates via high-temperature roller coating. They deliver rich, full color tones with strong visual impact and remain the most recognizable warning-colored sheets within the construction industry.
Base materials are standard galvanized steel strips that comply with national specifications, with zinc coating weight ≥80g/㎡. The front coating film thickness is 20μm, while the rear protective coating measures 12μm, with coating adhesion reaching Level 0. The coating will not crack or flake after bending fabrication. This material fits all enclosure structures including roofs, wall panels, site barriers and emergency auxiliary constructions.

Product Core Introduction
The large red pre-coated color steel plate is produced by a high-weather resistant polyester topcoat + hot-dip galvanized substrate high-temperature roller coating process. It has a rich and full color and strong visual impact. It is the most recognizable warning color plate in the construction field. The steel plate substrate is made of national standard galvanized steel strip, the zinc layer weight ≥80g/㎡, the front coating film thickness is 20μm, the back protective coating is 12μm, the coating adhesion reaches level 0, the bending process cannot crack or remove paint, and it is suitable for all scenes of enclosure structures such as roofs, walls, enclosures, and emergency supporting buildings.

Adapt to usage scenarios (solve the pain points of scenario matching)
It focuses on warning buildings, fire-fighting facilities, factory emergency channel enclosures, logistics park landmark factories, and the facades of red cultural and tourism buildings. Red has full recognition in low-visibility environments such as long distances, smog, rain, etc., and can quickly divide functional areas to avoid safety hazards in factories and parks; at the same time, it is suitable for the roof renovation of red-themed cultural and tourism towns and antique commercial buildings to create visually focal buildings.

Core performance advantages (addressing long-term usage pain points)
UV-resistant fading: Adding a special red color-resistant color-changing paste solves the problem of darkening and whitening of traditional red boards outdoors for 3-5 years. The color uniformity of high-light areas that have been used for more than 8 years still remains above 90%;
Resistant to industrial dust pollution: The dense surface coating is hydrophobic, and the plant coal ash and rust dust can be cleaned by rainwater flushing without frequent manual maintenance;
Structural stability: The tensile strength of the plate is ≥270MPa, it is resistant to typhoon and blizzard loads, and can be used stably in coastal light salt spray environments.

Purchase decision advice (precise selection reference)
Suitable for projects that pursue strong visual recognition and safety warning functions, it is preferred for exposed roofs and exterior wall enclosures; if it is used for southern open-air roofs exposed to high temperatures, it is recommended to upgrade the silicon-modified polyester coating to further extend the weather resistance life; when purchasing, 0.3-1.2mm thickness and corrugated/flat plate pattern can be customized on demand, supporting fixed-length opening and leveling to reduce on-site cutting losses.

Common usage questions and answers
Q: Will red color steel plates fade quickly after being exposed to the sun?
A: Ordinary red plate color paste has poor weather resistance. This model uses imported weather-resistant color paste, paired with a sealing primer to block ultraviolet rays. It is resistant to fading in ordinary outdoor environments with a life of ≥8 years. Fluorocarbon coating solutions can be upgraded in high ultraviolet areas.
Q: For use in fire-fighting buildings, does it comply with regulatory requirements?
A: The board material has passed the building envelope material inspection, has a fire resistance level of B1, and the red visual effect meets the appearance specifications of fire warning buildings. A complete inspection report can be provided
