RWI is distinctive among structural steel fabricators

The structural steels we fabricate include:

Carbon steels

• A36 - structural shapes and plate
• A53 - structural pipe and tubing
• A500 and A501 - structural pipe and tubing
• A529 - structural shapes and plate

HSLA steels

• A441 - structural shapes and plates
• A618 - structural pipe and tubing

RWI is also among the region's leading stainless steel fabricators. We manufacture equipment for the food, pharma and chemical industries, also HVAC.

The stainless steel grades we fabricate most are:

• Type 304 / 18/8 stainless steel
• Type 304L with lower carbon content for greater weldability
• Type 316 - for food, pharma and marine projects
• Type 316L (A4) - extra low carbon 316, for pressure vessels

Although we are best known as structural steel fabricators, (and stainless steel fabricators) we also provide aluminum fabrication, and we manufacture using special alloys (Inconel, Hastelloy) and thermoplastics.

Plastic fabrication uses these materials:

• Polypropylene
• PVDF
• CPVC
• Polyethylene
