Analysis of Types, Colors, Applications and Construction
Convenience of Color Steel Coil Roll-Formed Tiles
I. Types of Color Steel Coil Roll-Formed Tiles: Classified by
Process and Application
Based on differences in cold rolling forming processes and
application scenarios, color steel coil roll-formed tiles can be
divided into three mainstream categories, each with significant
differences in structural design and performance focus:
Roof-Specific Tiles
Represented by trapezoidal tiles and angle-lock tiles. Trapezoidal
tiles have a trapezoidal cross-section, with a wave height of
15-30mm and an overlap width of 50-80mm. They are suitable for
factory roofs with a slope of 15°-30° and enable rapid installation
due to their simple structure. Angle-lock tiles feature a
interlocking design, with a wave height of 40-60mm. They enhance
wind resistance through hidden buckle interlocking of adjacent
tiles, and are mostly used for roofs of large-span logistics
warehouses and stadiums, capable of withstanding winds below level
12.
Wall-Specific Tiles
Mainly including tongue-and-groove tiles and flat lock tiles.
Tongue-and-groove tiles are designed with grooves and tenons on the
sides; during installation, they form airtight walls through
mortise-tenon splicing. Suitable for exterior walls of light steel
villas and factory enclosures, they can effectively prevent
rainwater penetration. Flat lock tiles adopt a horizontal locking
structure, with a single tile area up to 1.2m×0.6m. They have
strong decorative properties, are often used for exterior wall
decoration of commercial buildings, and can be matched with
wood-grain or stone-grain coatings to simulate natural materials.
Special Functional Tiles
Including anti-corrosion tiles and heat-insulating tiles.
Anti-corrosion tiles add an epoxy primer to the PE/PVDF coating,
with a salt spray resistance of over 1000 hours, making them
suitable for chemical workshops and buildings in coastal areas.
Heat-insulating tiles are laminated with 50-80mm thick polyurethane
foam or glass wool in the middle, with a thermal conductivity
≤0.03W/(m·K). They can reduce indoor temperature by 5-8℃ in summer
and are widely used in agricultural greenhouses and food processing
factories.
II. Colors of Color Steel Coil Roll-Formed Tiles: From Coatings to
Color System Selection
Colors are mainly determined by surface coatings and need to be
matched according to application scenarios and functional
requirements. The core characteristics are as follows:
Correlation Between Coatings and Colors
- PE Coating (Polyethylene): Enables basic color systems, such as crimson, ocean blue, and
off-white. It has high color saturation and low cost, suitable for
ordinary factories and temporary buildings.
- PVDF Coating (Polyvinylidene Fluoride): Offers stronger weather resistance, and can be formulated into
metallic colors (e.g., silver gray, champagne gold) and dark color
systems (e.g., jet black, dark brown). Its UV aging resistance
lasts for more than 15 years, making it mostly used for exterior
walls of high-end villas and commercial buildings.
- HDPE Coating (High-Density Polyethylene): Focuses on matte color systems, such as light gray and off-white,
suitable for wall surfaces of office parks with requirements for
light reflection.
Common Color Systems and Application Scenarios
- Industrial buildings mostly use light color systems such as
off-white and ocean blue, which can reduce sunlight absorption and
lower roof temperature.
- Civil buildings like light steel villas often use warm color
systems such as crimson and beige to enhance the warmth of living
spaces.
- Agricultural greenhouses mostly adopt transparent or off-white
coatings to ensure sufficient light.
- Special scenarios such as chemical parks require eye-catching
colors like orange-red and bright yellow, which have both warning
functions and anti-corrosion properties. In addition, colors can be
customized according to the RAL color card to meet the personalized
needs of projects.
III. Applications of Color Steel Coil Roll-Formed Tiles: Covering
Multi-Field Construction Needs
With the advantages of light weight and strong weather resistance,
color steel coil roll-formed tiles are widely used in the
construction field. The core application scenarios include:
Industrial and Warehousing Buildings
For factory roofs and warehouse sheds, trapezoidal tiles or
angle-lock tiles are the first choice. They have a large
single-tile area (up to 1.5m×0.8m) and high installation
efficiency, and can adapt to large-span steel structures. For
example, in a 30-meter span machinery factory, using angle-lock
tile roofs can reduce the number of supporting components.
Tongue-and-groove tiles are mostly used for enclosures; after
splicing, no additional plastering is required, shortening the
construction period.
Civil and Commercial Buildings
For exterior walls of light steel villas, tongue-and-groove tiles
or flat lock tiles are commonly used, matched with PVDF metallic
coatings, which have both aesthetics and durability. For the podium
exterior walls of commercial complexes, special-shaped roll-formed
tiles (e.g., arc-shaped, wave-shaped) can be used, combined with
customized colors to create a unique architectural appearance. For
roofs of rural self-built houses, PE-coated crimson or dark gray
tiles are mostly selected, featuring high cost-effectiveness and
low maintenance costs.
Special Scenario Applications
- Agricultural greenhouses use heat-insulating tiles to achieve a
balance between heat preservation and light transmission, ensuring
crop growth.
- Chemical workshops and sewage treatment plants select
anti-corrosion tiles to resist corrosive gases and rainwater
erosion.
- For temporary buildings such as construction enclosures and
prefabricated houses, thin color steel roll-formed tiles (0.2-0.3mm
thick) are commonly used, which are lightweight, easy to assemble
and disassemble, and reusable.
IV. Construction Convenience of Color Steel Coil Roll-Formed Tiles:
Highlighting Processes and Advantages
Compared with traditional tiles, color steel coil roll-formed tiles
have a simplified construction process and low requirements for
sites and technology. The core convenience is reflected in the
following aspects:
Simple Construction Process
On-site construction only requires three steps:
- First, cold-roll the color steel coil into tiles using a dedicated
roll-forming machine (tile size can be customized according to roof
length, no cutting required).
- Then, lay the tiles in sequence: roof tiles are fixed by
overlapping or interlocking, while wall tiles are fixed with
self-tapping screws after mortise-tenon splicing.
- Finally, seal the joints (using butyl tape or silicone adhesive). A
single construction team (3-4 people) can lay 300-500㎡ per day,
which is 3-4 times the construction efficiency of traditional
tiles.
Low Requirements for Tools and Sites
- No large hoisting equipment is needed; the roll-forming machine can
operate directly on the construction site, especially suitable for
narrow sites.
- Fixing only requires conventional tools such as electric drills and
self-tapping screws; no professional masonry skills are needed, and
ordinary construction workers can operate after simple training.
- The tiles are lightweight (8-15kg per square meter), easy to
transport, and reduce labor costs.
Convenient Post-Maintenance
- If local tiles are damaged, only the fixing screws in the
corresponding area need to be removed, and new tiles can be
replaced and re-fixed without large-scale renovation.
- When the surface coating is dirty, it can be wiped with clean water
or neutral detergent. The maintenance cycle is long (PE coating
needs to be inspected every 5 years, PVDF coating every 10 years),
significantly reducing post-maintenance costs.
