Company Introduction

Northern Porcelain Capital - Ruierfa Enamel was established in 2012, covering an area of 120 acres with a registered capital of 100000000 yuan. It is located in Xicheng Industrial Zone, Luannan County, Tangshan City, Hebei Province. Ruierfa Quality is the result of more than 200 employees and an elite team of more than 20 high-tech talents. It is a huge research and manufacturing base for enamel steel plates. Since its establishment, the company has only focused on the research and development, production, and sales of enamel steel plates.

Through the continuous efforts of the Rui Er Fa elite team, over 10 years of operation, we have improved and improved our management system and quality control policy, and have passed ISO9001:2015 The full system certification of ISO14001:2015 and ISO45001:2018 marks that Riel Law has taken the lead in entering a standardized, standardized, and refined operating mode in the industry, and is a model in the industry. The quality of Rui Er Fa enamel has successively passed the National Building Quality Supervision and Inspection Center, National Building Materials Research Institute, National Building Engineering Quality Supervision and Inspection Center Third party supervision and testing institutions such as REL, CTIC, and SGS conduct testing and fully comply with national, European, and British standards.

Professional quality cannot be achieved without advanced production equipment. Rui Er Fa has introduced American Nordson dry enamel powder electrostatic spraying equipment, using a scientific two spray and one firing process, and equipped with automated laser cutting machines, flexible sheet metal bending centers, and robot bending systems. It can accurately control the cutting size and shape quality of rough steel plates. The first production line has a monthly production capacity of 50000 square meters and an annual output of 600000 square meters. The second production line is planned to be put into operation by the end of 2025. At that time, the annual production of enamel steel plates by Rierfa will exceed one million square meters, striving to be the first in national production capacity, quality, and service.

Introduction to Enamel Steel Plate

Enamel steel plate is a composite material formed by a new electrostatic dry powder coating process and high-temperature firing of zero carbon steel plate and special functional inorganic non-metallic materials, which creates a strong chemical bond between the steel plate and the enamel coating.

Enamel coating on the surface of steel plates can prevent rusting, prevent the formation of an oxide layer on the surface when heated, and resist the erosion of various liquids. Enamel products are not only safe and non-toxic, but also exhibit excellent properties such as high hardness, high temperature resistance, wear resistance, and insulation on metal bodies under specific conditions when coated with enamel.
