SEPP steel is a composite material of Special Engineering Plastics and steel, which combines the light weight and corrosion resistance of engineering plastics with the high strength and wear resistance of steel, and is widely used in many industrial fields.
Main characteristics
High strength: Steel provides excellent mechanical strength and is suitable for high load environments.
Corrosion resistance: The engineering plastic layer effectively resists chemical corrosion and prolongs service life.
Light weight: Compared to pure steel, SEPP steel is lighter and easier to transport and install.
Wear resistance: Surface engineering plastic layer enhances wear resistance, suitable for high wear environment.
Insulation: Engineering plastics have good insulation properties and are suitable for electrical applications.
Application field
Automotive industry: For the manufacture of lightweight, corrosion-resistant components such as body structures and chassis components.
Construction industry: Used for building structures with high weather resistance and corrosion resistance requirements.
Electronic and electrical: suitable for the shell and bracket of electrical equipment with high insulation performance requirements.
Chemical industry: Used for pipes, tanks and equipment that are resistant to chemical corrosion.
Mechanical manufacturing: Used for mechanical parts with high wear resistance requirements, such as gears and bearings.
Manufacturing process
The manufacture of SEPP steel usually involves the following steps:
Steel pretreatment: cleaning and surface treatment to improve adhesion.
Engineering plastic coating: The engineering plastic is coated on the steel surface by extrusion, injection molding or spraying.
Composite treatment: The use of hot or cold pressing to make the plastic and steel tightly combined.
Post-treatment: Cooling, cutting and surface treatment to ensure finished product quality.
Advantages:
Excellent comprehensive performance, suitable for a variety of application scenarios.
Extend service life and reduce maintenance costs.
Lightweight design helps to save energy and reduce emissions.
