►Quality Assurance:
Lite Refractory is committed to high quality standards for all its products and services. With its thirst on State of the art technology at every level and a wide range of products, Lite Refractory can provide ideal solutions for the stringent requirement of the customer. Backed by decade of experience in different industries, and close association with customers,Lite Refractory will always bring new products which will give better life and value to the user.

The quality assurance system consists of the following steps:
a.Inspection and Control of incoming raw materials:According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.Inspection and control of the process:During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Inspection of product Standardization of quality of each product by process control and experimentation.
d.Taking corrective measures whenever deviations are noted.
e.Quality audit by quality management.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
