Our Advantages
Complete range
For the use of color steel coils, we have to choose different types
of color steel coils to manufacture different PPGI. Speaking of
this, I have to briefly introduce the types of color steel coils,
which are divided into five categories. That is, home appliances,
optical materials, decorative materials, building materials, and
packaging. Among them, the production process of color steel coils
for home appliances is the most delicate and perfect.
Good performance
Zhengde color coated steel plate refers to the coating product
obtained by applying organic paint to the surface of thin steel
plate. PPGI has good anti-corrosion and decorative properties, as
well as the good formability and processing properties of organic
polymers and steel plates.
5S management
Before PPGI production, each post cleans the surrounding
environment, ground sanitation, equipment spot inspection and each
roller surface that directly affects the surface quality of the
product in the working area according to the "Workshop 5S
Management System" to ensure personal safety. At the same time,
prepare tools, auxiliary materials, raw materials, etc. within the
specified time. Ensure that the ground in the work area is free
from dust, water and oil, ensure that the equipment is in the best
condition and that the materials are used correctly.
Strictly check
PPGI image defects, surface defects, trace defects, edge defects,
gold plating defects, size defects, coating defects, uneven
defects, contamination defects, coating uneven defects, process
defects, coating surface defects, physical property defects.
Applications:
PPGI Steel Coil is widely used in industries such as construction,
home appliances, automotive, and agriculture. It is commonly used
for roofing, wall cladding, cold storage facilities, appliance
exteriors, automotive body panels, and corrosion-resistant
industrial equipment.
These titles and descriptions focus on the product's key selling
points like corrosion resistance, customization, and wide
industrial applications, while adhering to Google Ads best
practices.
