These are structural steel sheets that stand out for their strength and hardness. Their quality, processing requirements and properties are governed by ASTM/ASME regulations. Due to their versatility, common ASTM/ASME structural steel sheets are widely used in a number of applications. You will use them, for example, on bridge and building structures, heavy machinery, crane arms or boilers and pressure vessels.

ASTM/ASME Properties and Uses of Structural Steel Sheets
Sheets made of structural steel stand out especially for their strength and rigidity. It is also suitable for high temperature operation. They are well weldable by all welding processes including shielded arc welding, oxygen welding or gas arc welding. Technical requirements of structural steel sheets are specified by the ASTM standard, or ASME's regulations are very similar, in some cases virtually identical. ASTM (denoted with the letter A before the numbers) covers general material properties, ASME (designated SA) is based on ASTM and specifies requirements for pressure applications.
The properties of sheet metal offer a wide range of uses. They are suitable for the construction of bridge and building structures, but you will also find them on construction machines, crane arms, transmission towers or trucks. ASME materials are then used in pressure equipment such as boilers, heat exchangers, pressure vessels and large tanks for liquids and gases.
Choose from a wide range of sizes. We supply sheets in the following dimensions:
- length: max. 18,000 mm,
- width: 1000-3200mm,
- thickness: 5-100 mm,
- weight: max. 12,500 kg.
The stated dimensions are only approximate. The resulting appearance depends on the combination of individual parameters and material specification. Upon agreement, we are able to produce sheet metal up to a length of 21,000 mm and a thickness of 200 mm. For more information contact us.
