Main Application

Building Structures

Used in bridge steel structures, factories, warehouses, and frame constructions.

Advantages: high strength, lightweight, excellent weldability, suitable for large-scale structural projects.

Bridges & Infrastructure

Bridge girders, steel trusses, and load-bearing structures.

Grades 50–65 can be selected based on load requirements, meeting high-strength design standards.

Industrial Components

Heavy machinery chassis, supports, racks, and equipment frames.

Benefits: good wear resistance and ability to bear heavy loads.

Low-Temperature or Harsh Environment Structures

Micro-alloying elements (Ni, Cu) can be added to improve low-temperature toughness or corrosion resistance.

Marine & Transportation Equipment

Ship decks, vehicle chassis, and cargo compartment structures.

HSLA properties make the plates lightweight yet high-strength.

Custom Structural Applications

Steel frameworks, industrial platforms, and support beams.

Thickness, length, and width can be customized to meet special design requirements.

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

1) Branch Office - Spanish-speaking support, customs clearance assistance, etc.

Royal Steel Group Premier Manufacturer of High-Quality Steel Sheets and Plates

2) Over 5,000 tons of stock in stock, with a wide variety of sizes

3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging

Packing And Delivery

1️⃣ Bulk Cargo
works for large shipments. The plates are loaded directly onto ships or stacked with anti-slip pads between the base and the plate, wooden wedges or metal wires between plates and surface protection with rain-proof sheets or oil for rust prevention.
Pros: High payload, low cost.
Note: Specialized lifting gear is needed and condensation and surface damage must be avoided during haulage.

2️⃣ Containerized Cargo
Good for medium to small shipments. The plates are packed one by one with waterproofing and anti-rust treatment; a desiccant can be added in the container.
Advantages: Provides superior protection, easy to handle.
Drawbacks: Higher cost, decreased container loading volume.

Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.

We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling. This guarantees the H-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!
