Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

EN steel grade S235JR material, Q890D steel plate is quenched and tempered steel for high-strength structure, the implementation standard: GB/T 16270. In the Q890D steel grade, "Q" means yield, "890" means yield value, and "D" means grade level. The equivalent material of Q890D is EN S890Q steel. The size, shape, weight and allowable deviation of Q890D steel plate shall meet the requirements of GB/T709. Q890D steel plate delivery status (heat treatment): quenching and tempering.

In 2021, China's steel structure industry will continue to maintain rapid development. As the proportion of prefabricated buildings in the country's newly built buildings continues to increase, the scale of investment in "new infrastructure" has expanded.
