Royal Steel Group Advantage（Why Royal Group Stands Out for Golbal Clients?）

ASTM A992 Grade 50 Standard – Our I beams are manufactured to the ASTM A992 standard, which is a widely recognized grade for steel beams making them suitable for use in construction with a minimum yield strength of 50 ksi (345 MPa).

American Standard Sizes – Both S-shape and American standard I-beams come in a variety of sizes, and custom lengths can be ordered.

Strict Quality Control – Dimensional inspection or material testing and third party inspection by SGS/BV can be arrange as per project requirement.

Mill Test Certificate - MTC could be issued with critical material and mechanical test data for project documentation and quality assurance.

Custom Processing – We provide cutting, drilling, welding and other processing services as per customer drawing.

Dependable Global Supply – Royal Steel Group is well equipped to handle international inquiries for steel and other metal products by providing export packaging, flexible shipping options and experienced metal supply services.

Packaging and Shipping

Steel I-beams are tightly banded for export. Based on beam size, volume, destination, and end customer needs, the products may be delivered in containers, on bulk vessels or by other means of transportation.

Protective packaging and tight bundling minimize shifting and damage during loading, shipping and unloading.
