Steel Plate Standards
Structural steel shape properties, such as composition and strength are regulated by agreement between parties who choose to accept international standards. These international standards are created by formally recognized regulating boards, often times comprised of worldwide, volunteer members within respective industries. It is customary for American made steel plate manufacturers to choose to have their hot rolled plates recognized by several of these governing bodies, such as ASTM International, ANSI, AISC, AISI, ASCE, ASME, and the AWS along with their European Union standards counterparts.
| ASTM International | American Society for Testing and Materials |
| ANSI | American National Standards Institute |
| AISC | American Institute of Steel Construction |
| AISI | American Iron & Steel Institute |
| ASCE | American Society of Civil Engineers |
| ASME | American Society of Mechanical Engineers |
| AWS | American Welding Society |
PGI stocks large quantities of 96″ x 240″ in a range of thicknesses up to 8″ thick and larger. We inventory full sheets of plate that adhere to international standards specifications regulated by AISI and ASTM. We also inventory small quantities of structural steel angle, channel, I-beam, steel bar, and hollow structural sections of tubing, including steel pipe and square tubing for fabricated weldments. When fabricating steel weldments, we adhere to the standard practices as specified by ANSI, AISC, ASCE, the American Society of Mechanical Engineers, and the American Welding Society.
Cash Flow Improvement
Customers save a considerable amount of production time by taking advantage of our Single Source Solution approach. At the same time you receive a very competitive price, you’re also able to improve your cash flow. When you have multiple vendors process your steel orders, often times, you’ll have to pay for parts of the production cycle prior to receiving your goods. One of the greatest benefits from using our single source solution approach to cutting, grinding, machining, and fabricating steel plate products in-house, under one roof, is that you, the customer, will have the benefit of shipping finished products to your customers prior to receiving your bill for the materials.
