What lengths of structural steel are available?
AISS stocks many structural steel products in 20-foot and 40-foot lengths. Available lengths vary by product, size, and material, so contact the Janesville team to confirm current inventory for your project.
Can AISS cut structural steel to the length I need?

AISS carries wide-flange, junior, and I-beams with heights ranging from 3 inches to 18 inches, lengths up to 40 feet, and weights up to 50 pounds per foot. Availability varies, so it's best to check current stock when requesting a quote.
What sizes of steel channel are available?
AISS stocks bar channel and standard structural channel in sizes ranging from 1 inch to 18 inches in height. Carbon steel, aluminum, and stainless steel options are available, and channel can be cut to the length required for your project.
What's the difference between a steel beam, channel, and angle?
Each structural shape serves a different purpose. Beams are commonly used for heavier load-bearing applications. Channel has a C-shaped profile that works well for framing, supports, and reinforcement. Angle has an L-shaped profile and is commonly used for bracing, frames, supports, and general fabrication. The best choice depends on the loads, connections, and design requirements of the project.
Can I buy just one piece of structural steel?
Yes. AISS serves customers who need anything from a single piece to larger quantities of steel. There is no minimum length or quantity requirement, and material can be cut to length at the Janesville facility.

Yes. AISS offers on-site delivery from its Janesville facility. Local and regional deliveries can be arranged, and longer-distance delivery may also be possible depending on the order and delivery costs. Contact AISS with your material list and delivery location to discuss options.
