PPGL Galvanized Color Steel Coil
Our Galvanized Pre-painted Steel Coil (PPGL) is a high-performance
metal material widely used in global construction, industrial and
household sectors. It adopts premium hot-dip galvanized steel as
the substrate, which goes through a professional surface
pretreatment process including degreasing, pickling, phosphating
and passivation. This treatment removes surface contaminants and
oxides, improving coating adhesion and durability for long-term
use.
Using advanced roller coating technology, both sides of the coil
are coated with high-quality organic paint such as polyester,
silicon-modified polyester or PVDF. The coating thickness is
uniformly controlled within 10–30μm, providing good color stability
and weather resistance. The finished material can resist UV
radiation, rain erosion and moderate chemical exposure, maintaining
a uniform and bright appearance over extended periods under normal
outdoor conditions, without obvious fading, peeling or cracking.
In terms of mechanical performance, the product features good
toughness and workability. The galvanized layer (zinc coating
weight 40–275g/㎡) offers effective anti-corrosion protection,
extending the service life compared with ordinary carbon steel
coils. It can be easily bent, cut, stamped, formed and welded
without damage to the coating, supporting efficient fabrication and
installation for different project requirements.
A variety of customizable options are available to meet diverse
customer needs. Substrate thickness ranges from 0.12mm to 1.2mm,
width from 800mm to 1250mm, and coil weight from 2 to 5 tons. We
provide a wide range of standard RAL colors, and custom color
matching is acceptable based on customer samples. Different surface
finishes such as glossy, matte and textured can also be arranged
upon request.
Typical applications include roofing, wall cladding, partitions and
ceilings for industrial plants, warehouses and residential
buildings. It is also widely used for home appliance casings,
container liners, metal furniture and decorative materials.
We implement consistent quality management throughout production,
from raw material selection to final inspection, to ensure
compliance with international standards such as ASTM, EN, GB and
JIS. The products have been supplied to many regions and are widely
recognized by customers for stable performance and reliable
quality. We also provide professional technical support and
after-sales service to assist customers in project planning and
daily use.
