HSS & Tube Bending
Pacific Roll specializes in HSS tube bending and structural tube rolling for fabricators, contractors, architects, engineers, and manufacturers. We work with square HSS, rectangular HSS, round tube, and structural tube sections — from standard sizes through large and jumbo sections.
Based in Riverside, California, we serve the Inland Empire, Southern California — including Los Angeles, Orange County, and San Diego — as well as Arizona, Nevada, and customers throughout the United States.
We handle difficult and custom tube geometries. Send us your drawings and we will evaluate the appropriate forming process for your project.

HSS Tube Bending & Rolling
HSS tube bending and tube rolling are related but distinct processes. Rolling uses a set of dies or rolls to progressively form a section into a continuous curve — the method used for arches, rings, and long-radius curves where the bend spans a significant length of the member. Bending uses a different tooling setup to form a discrete angle or short-radius curve at a specific point along the member. The appropriate forming method depends on the section size, wall thickness, material grade, required radius, bend angle, and overall geometry of the part.
Pacific Roll works with the full range of structural tube sections:
- —Square HSS
- —Rectangular HSS
- —Round tube
- —Structural tube
- —Large and jumbo sections
- —Curved structural members
- —Arches and partial arches
- —Full rings and ring segments
- —Custom and complex geometries
If you are not sure which process applies to your project, send us your drawings. We will review the geometry and recommend the right approach before quoting.
Large HSS Tube Bending
Pacific Roll operates equipment capable of rolling and bending large HSS sections that most shops cannot handle. We roll square and rectangular HSS up to and including jumbo sections — 14×14, 16×16, 20×12, 20×20, and similar heavy-wall tube — as well as rectangular sections such as 12×8, 16×8, 20×4, and 20×8.
Actual capability depends on a combination of factors:
- —Section dimensions
- —Wall thickness
- —Material grade
- —Required radius
- —Bend angle
- —Orientation
- —Quantity
- —Overall geometry
A section that rolls easily to a large radius may require different tooling or additional passes at a tighter radius. Send us your section designation, wall thickness, and required radius and we will tell you directly whether we can form it and what to expect. We would rather review your drawings early than have you discover a forming problem after the project is awarded.
Multi-Plane & Multi-Radius Tube Bending
Some projects require tube that changes direction in more than one plane, or that incorporates multiple radii within a single member. Helical stair stringers, curved ramps, twisted architectural frames, and specialty structural elements often fall into this category.
Pacific Roll can evaluate multi-plane and multi-radius tube bending projects. Where the geometry requires it, we use custom jigs and fixtures to verify the shape during and after forming. If your project involves geometry that goes beyond a standard single-radius bend, contact us with your drawings or CAD files and we will work through the forming approach with you before providing a quote. See also our Spiral Bending page for helical and multi-plane structural applications.
Structural Tube Bending
Structural steel fabricators regularly need curved HSS and tube components that their own shops are not equipped to produce. Pacific Roll provides structural tube bending as a specialized subcontract operation — you maintain control of the rest of the fabrication project while we handle the rolling and bending work.
Common structural tube bending applications include:
Curved beams
HSS curved the strong way or weak way for structural framing.
Arches
Full and partial arches for roof systems, entries, and feature structures.
Canopies
Curved HSS framing for architectural canopies and shade structures.
Architectural structures
Exposed structural tube for feature elements and building facades.
Stair systems
Curved and helical stair stringers in HSS and structural tube.
Specialty structures
Entertainment venues, theme parks, and custom industrial structures.
Industrial equipment
Curved tube components for equipment frames and support structures.
Building structures
Curved perimeter framing, mezzanine edges, and curtain wall support.
For wide-flange beams and other structural sections, see our Structural Steel & Beam Rolling page. For large-section hot bending, see Induction Bending. For data-center construction projects, see Data Center Tube Bending.
Architectural & AESS Tube Bending
Architecturally Exposed Structural Steel (AESS) demands consistent geometry and a clean appearance. When curved HSS will be visible to building occupants — in a lobby, atrium, canopy, or feature structure — the forming quality has to meet a higher standard than concealed structural work. Surface marks from the rolling process, inconsistent curvature, or cross-section distortion are all visible on exposed tube and unacceptable on AESS applications.
Pacific Roll works with architects, engineers, and fabricators on AESS tube bending projects throughout Southern California and beyond. We understand that on an exposed structural element the geometry has to be right — not close — and we work to the tolerances your project requires.
Tube Bending for Structural Steel Fabricators
If you are an estimator or project manager at a structural steel fabrication shop, you already know that tube rolling and bending equipment is expensive, specialized, and not something most shops own. When a project calls for curved HSS or structural tube, you need a reliable subcontractor who can deliver accurate parts on schedule without creating problems for the rest of your fabrication sequence.
Pacific Roll works directly with fabrication companies as a specialized tube bending subcontractor. Your shop handles connections, welding, coating, and delivery. We handle the rolling and bending work and ship finished pieces back to your shop ready for fit-up — or directly to the job site when that works better for your schedule.
Send us your drawings early in the estimating process. We can review feasibility and provide pricing while you are still putting together your bid — so there are no surprises after the project is awarded. We also offer CNC plasma cutting and full fabrication services when your project benefits from combining operations in one place.
