The construction convenience of color-coated coils is one of their
core advantages for wide application, which is specifically
reflected in five dimensions:
lightweight base material, flexible splicing methods, compatibility
with general tools, low construction threshold, and adaptability to
complex scenarios.
The specific performance and advantages of each dimension are as
follows:
Color-coated coils use cold-rolled or galvanized steel plates as
the base material. Although they have a certain structural
strength, their weight per unit area is only 1/5 to 1/10 that of
traditional building materials (e.g., stone, concrete slabs). For
example, the weight of a conventional color-coated coil is
approximately 10-20 kg per square meter, while that of a stone
curtain wall can reach 80-150 kg per square meter.
- During construction, heavy hoisting equipment is not required, and
handling can be completed manually or with small machinery. This is
particularly suitable for high-rise construction or narrow-space
construction scenarios, reducing equipment rental costs and site
constraints.
- The lightweight property also reduces the load pressure on the main
building structure, eliminating the need for additional structural
reinforcement and indirectly shortening the pre-construction
preparation period.
Deep-processed products of color-coated coils (such as color steel
plates, sandwich panels, and corrugated plates) feature highly
standardized splicing designs, eliminating the need for complex
on-site processing. Common splicing methods include:
- Snap-fit splicing: Some color steel plates come with prefabricated interlocking
edges. On-site, only manual or electric tools are needed to snap
the edges of the plates together, without requiring additional
seals. This operation can be completed by 1-2 workers, and the
splicing efficiency is more than 30% higher than that of
traditional welding.
- Bolt connection: For large components (e.g., factory wall panels, carriage
plates), they can be directly fixed to keels using self-tapping
screws or expansion bolts. This method ensures precise positioning
and detachability, facilitating replacement during later
maintenance or renovation.
- Lap splicing: Products like corrugated plates can achieve waterproof sealing
through overlapping laps, without the need for professional welding
skills, lowering the skill requirements for workers.
The processing and installation of color-coated coils can be
completed with conventional construction tools, eliminating the
need for investment in specialized equipment and reducing
construction equipment costs:
- For cutting, ordinary hand-held electric saws or plate shears can
be used for precise cutting, without the need for large laser
cutting equipment.
- Bending and hole-drilling can be performed using manual bending
machines or small punch presses, allowing on-site fine-tuning
according to actual dimensions.
- For fixation, only basic tools such as electric drills and wrenches
are required, which can be easily obtained even in remote
construction sites.
Compared with traditional building materials (e.g., tile laying
requires leveling and joint pointing; stone installation requires
grouting), the construction process of color-coated coil products
is much simpler:
- No complex base treatment is needed: Only the installation base
(e.g., keels, steel frames) needs to be leveled, eliminating the
time required for plastering, leveling, and waiting for drying.
- Modular installation: Most deep-processed color-coated coil
products come in standardized sizes (e.g., 1.2m × 3m color steel
plates), which can be directly spliced according to design
drawings. This reduces the frequency of on-site measurement and
cutting. A single worker can install 50-80 square meters per day,
significantly shortening the construction period (e.g., the wall
installation of a small factory can be completed in only 3-5 days,
which is 2-3 times faster than traditional brick wall
construction).
The organic coating on the surface of color-coated coils has UV
resistance and acid-alkali resistance. During construction, there
is no need to worry about temporary exposure to rain, sand, or dust
causing base material rust or coating damage:
- Unlike wood or steel, there is no need for on-site anti-corrosion
paint brushing, reducing one construction process.
- The coating is less likely to crack or peel in low-temperature and
high-temperature environments (-30℃ to 60℃), adapting to the
climatic conditions of different regions. There is no need to
adjust the construction plan according to seasons, improving
construction flexibility.
