Overview
Standard I-Beams feature tapered flanges and a central web engineered to deliver efficient strength and reliable load-bearing performance across industrial and structural applications. Their classic “I” profile is ideal for long-span support systems and reinforced stainless frameworks.
I-Beams provide strong bending resistance along the major axis, making them suitable for joists, frames, platforms, and vertical column-like support systems.
Stainless steel variants offer corrosion resistance, enabling use in environments where strength and durability must be maintained over decades of exposure.
Engineers rely on I-Beams for consistent performance under heavy load conditions and for structural designs requiring predictable manufacturing tolerances.
Makers use I-Beams for machine frames, supports, gantry systems, and precision-aligned mechanical structures.

Technical
Standard I-Beams are produced to ASTM structural standards with tapered flanges that reduce weight while preserving load capacity.
The shape resists bending along the major axis, enabling efficient support of vertical and horizontal loads.
Stainless variants are available in 304/304L and 316/316L, supporting industrial, architectural, and corrosive environments.
The web and flange geometry create predictable mechanical behavior under shear, bending, and axial loading.
Material supports machining, drilling, tapping, grinding, welding, and precision assembly in structural frameworks.
Applications
Standard I-Beams are used for building frames, platforms, mechanical supports, and long-span structural members.
Architectural applications include visible stainless framing, decorative structural beams, and exposed support structures.
Industrial systems rely on I-Beams for conveyor supports, machine frameworks, reinforcement rails, and structural bracing.
Marine industries use stainless I-Beams for structural components exposed to corrosive environments.
Makers use I-Beams for heavy CNC structures, mechanical engineering projects, robotics platforms, and gantry designs.
Industries
Construction industries use I-Beams for framing, load-bearing systems, and structural reinforcement.
Architectural projects integrate I-Beams into exposed structural elements, stainless columns, and decorative framing.
Industrial fabrication uses I-Beams for equipment bases, frames, elevated platforms, and heavy-duty bracing.
Marine facilities use stainless I-Beams for long-life corrosion-resistant structural elements.
Makers use I-Beams for supporting high-weight CNC gantries, industrial machines, test rigs, and structural engineering prototypes.
Integration
Standard I-Beams integrate into structural assemblies using welds, structural bolts, plates, and precision-machined interfaces.
The tapered flanges support mounting brackets, rails, reinforcement plates, and linear guides in mechanical systems.
Machinists and fabricators rely on I-Beams to maintain straightness and load-bearing performance in equipment structures.
Stainless I-Beams support integration with tubing, plates, channels, and additional beam sections.
Makers combine I-Beams with robotics modules, CNC rails, lifting systems, and structural frameworks.
