The S20 series of new materials are free from corrosion protection, galvanization, paint spraying and maintenance, reduce production and processing links, free from repeated loading, unloading, and handling, and free from maintenance investment in the later period.

3. Excellent quality:

S20 series of new materials are fully equipped with the properties and characteristics of third-generation low-alloy new weather-resistant steel, featuring high strength and toughness, high plasticity, high corrosion resistance, green, environmental protection, energy saving and excellent welding and adaptive adjustment.Not only has the anti-corrosion performance far surpasses the traditional weathering steel, but also has the high strength low alloy performance.

4. Complete variety:

In terms of mechanical properties of S20 series of new materials, the new S20 series of new materials of the same strength level correspond exactly with normal steel, and the corresponding relation is :(s20-235), Q235, (s20-345), Q345, (s20-390), Q390, (s20-420), Q420, (s20-690), Q690 and so on.There are also all kinds of "H20 series new material welding materials" and "B20 series new material special bolt connecting parts".

For each batch of materials, the east China branch of China iron and steel research institute shall conduct sampling inspection and sample storage, and issue the "S20 series new material quality confirmation letter" to the S20 series new material using unit, so as to guarantee the quality and quality of the S20 series new material used!

S20 series of new materials and relative to the advantages of pu steel mainly: to effectively improve the corrosion resistance of steel, but not to change the original mechanical properties.The new S20 series materials and steel of the same strength level can completely achieve the strength substitution with the same specification on the mechanical property without changing the structure stress of the material.The designer can completely design according to the existing steel structure design specification, and replace with the S20 series of new materials of equal strength, and apply to the structure design system

7. Processing on demand:

S20 series of new material hot rolled sheet can be cold-rolled into various types of components such as moment tube, square tube, cold Angle steel, C shape steel series.Hot rolled sheet coil, middle plate can also be welded into H - shaped steel and T - shaped steel specifications.It can also be directly processed by steel mills into rebar, bar, high wire, i-beam, etc.

S20 series of new materials, in application, do not need pickling, galvanizing, sandblasting, painting anti-corrosion paint (except for color and appearance requirements), maintenance free, and the same life as the building.

In countries growing under the background of environmental standards and requirements, S20 series of new materials, whether in the comprehensive construction cost, or in the whole life cycle maintenance cost, and speed up the construction time limit for a project, have absolute advantages, is an upgrading generation new steel instead of common steel system, is a revolution of the steel structure materials.

9. Follow-up services:

Facing the reality of serious lag in application standards, standards and regulations of new materials in China, in order to overcome the bottlenecks in various applications of S20 series of new materials, experts from east China branch of China academy of steel research can cooperate with application parties and design institutes to carry out expert explanation and expert demonstration of S20 series of new materials.

10. Wide application:

It is suitable for the construction and application of Street Lamp, high lamp, yard lamp, solar lamp, lawn lamp, Landscape Lamp, traffic light, 5G Intelligent Lamp, tunnel lamp, monitoring lamp, decorative lamp, outdoor landscape sculpture.

Lighting industry application
