Galvanized prepainted steel coil with PE/PVDF coating, various
colors and sizes for construction and industrial use.
Our Galvanized Pre-painted Steel Coil (PPGL) is a reliable metal
material widely used in construction, industrial and household
applications. It is made from premium hot-dip galvanized steel
substrate, which undergoes a complete surface pretreatment process
including degreasing, pickling, phosphating and passivation to
enhance coating adhesion and long-term performance.
The coil is coated on both sides with high-quality organic paint
such as Polyester (PE), Silicon Modified Polyester (SMP) or PVDF
via advanced roller coating technology. With a controlled coating
thickness of 10–30μm, the product offers consistent color stability
and good weather resistance. Under normal outdoor conditions, it
maintains a uniform appearance over extended periods without
obvious fading, peeling or cracking.
The base galvanized layer, with zinc coating weight ranging from
30–275gsm, provides effective corrosion protection, helping to
extend service life compared to ordinary carbon steel. The material
also features good mechanical properties, including high yield
strength (195–420MPa) and excellent workability. It can be easily
bent, cut, stamped, formed and welded without damaging the coating,
supporting efficient fabrication for different project needs.
We offer a wide range of customizable options. Available thickness
ranges from 0.3–1.2mm, width from 800–1250mm, and coil outer
diameter from 1000–1500mm. A variety of standard RAL colors are
available, and custom color matching can be arranged based on
customer samples. Surface finishes including glossy, matte and
textured are also offered to meet diverse design requirements.
Typical applications include roofing, wall cladding, partitions and
ceilings for industrial plants, warehouses and residential
buildings. It is also suitable for home appliance casings,
container liners, metal furniture and decorative materials.
Our products are manufactured in compliance with international
standards such as AISI, ASTM, GB and JIS. We implement consistent
quality management throughout production, from raw material
selection to final inspection, to maintain stable performance. With
reliable quality and flexible specifications, the products have
been widely accepted by customers in many regions. We also provide
professional technical support to assist customers with project
planning and use.
