Welcome to Longero
Longero is Colorado's premier industrial custom steel fabricator, welding shop, and metal former. Since 1923 we have served the needs of Denver, Boulder, Ft. Collins, Colorado Springs, Pueblo, Grand Junction and surrounding areas in manufacturing large steel and stainless steel weldments.
Our full-service steel fabrication plant located in Denver offers a variety of services including;
LARGE SPECIALTY FABRICATIONS: Longero fabricates carbon steel, stainless steel, and aluminum weldments. We can fabricate in weights up to 80,000 pounds (40 tons). Common fabrication projects at our plant are skids, platforms, water control gates, atmospheric tanks (non-pressure vessels), bins, hoppers, transitions, clarifiers, process equipment, and spiral stair cases.
WELDING: Longero offers full service metal welding for both small and large projects. All welders meet requirements of AWS D1.1 and/or AWS D1.6, and can also be certified as needed to meet welding procedures for specific jobs.
Metals welded and/or processed:
- Carbon Steel (A36, A588, A709, A572, A516, AR Plate)
- Stainless Steel (304SS, 316SS, 409SS, 410SS)
- Aluminum (6061, 5052)
Weld processes used:
- FLUX-CORE (FCAW)
- MIG (GMAW)
- TIG (GTAW)
- Stick Electrode (SMAW)
- Submerged Arc Welding (SAW)
- Stud Welding (SW)
METAL PROFILE ROLLING: Longero utilizes three angle roll machines in-house to meet your steel bending needs of all sizes. We are Colorado’s most experienced shop for high-quality angle rolling, pipe rolling, square tube rolling, rectangular tube rolling, beam rolling and channel rolling.
PRESS BRAKE WORK: Longero’s four press brakes allow us to bend both small and large steel plates. Our largest 400-ton press brake can bend up to 1 ½” plate and is 14’ long. Typical projects on our press brakes included bending of heavy plate, forming stair pans, forming transitions, forming cones, forming square to rounds, forming channels, and forming angles. Our brakes can be used to step brake carbon steel or abrasion resistant (AR) plates to manufacture blades, buckets and other wear surfaces.
PLATE ROLLING WORK: Longero can roll steel plate on our three plate rolls. We can roll plate as thick as 1 ½”, and up to 5/8” plate in 12' long sections. Typical plate rolling projects include arc segments, repads, pre-fabricated railing, bucket liners, and spiral stair stringers from rectangular tubing, channel and plate.
SHEARING: Longero has two shears in-house. Our impressive large shear can cut up to 1 1/4" thick carbon steel and 3/4" stainless steel in 12' sections.
Longero is American Institute of Steel Construction (AISC) quality certified for Intermediate Bridge with a Fracture Critical Members endorsement. This certification demonstrates our commitment to quality and we are proud to be one of only a few fabricators in Colorado with this endorsement of our quality control program. We will be undergoing certification for the AISC’s new Hydraulic Structures certification in 2017.
