NewCon Steel® executes every hole and every connection by CNC in the plant, to a ±0.5 mm (±0.02 in) tolerance. All the job site needs is bolts, torque wrenches, and an erection crew.
NewCon Steel bolted structural steel is manufactured in cold-formed steel with a zinc-aluminum-magnesium (Zn-Al-Mg) coating of 275 g/m² total across both faces (0.90 oz/ft²). Its holes and connections are executed by CNC in the plant, so the frame is erected on site with bolts only: no field welding, no site galvanizing, and no coating touch-up.
Field welding introduces three risks that a bolted connection avoids by design.
The first is the coating. Welding coated steel destroys the metallic coating in the heat-affected zone. The field repair uses zinc-rich paint and does not reproduce the factory coating, so the building's most vulnerable point ends up at the structural connection.
The second is labor. Structural welding requires certified welders and weld inspection. On a Caribbean island or a remote site, finding and certifying that crew is a schedule risk that is rarely priced up front.
The third is variability. A bolted connection with a CNC-punched hole repeats identically at every joint. A field weld depends on the day, the weather, and the welder.
NewCon Steel executes the holes and connections by CNC in the plant, on steel that is already coated. On site, the structure bolts together.
Members are cold-formed from coil with a Zn-Al-Mg coating of 275 g/m² (both sides). They are then cut, punched, drilled, marked, and labeled by CNC straight from the structural model, to a ±0.5 mm dimensional tolerance.
The coating is applied to the originating coil, not in a dip bath after the part is finished. There is no site galvanizing and no batch galvanizing after fabrication, and no piece waits in line at a galvanizer.
All of it happens at the Centro Industrial PEB plant, Las Mañanitas, Panama City, on the same line that produces the LGS/CFS profiles.
The structure arrives numbered and sequenced. Erection is a positioning-and-torque operation, with no cutting, welding, grinding, or coating touch-up.
That changes the profile of the crew you need on site and removes the dependency on certified welders in destinations where they are scarce or expensive.
Bolted structure combines with LGS kits in hybrid systems: bolted portal frames form the skeleton and pre-assembled structural panels handle walls, floors, and roof, all on a single purchase order.
Hot-rolled steel structures (AISC 360) are designed by PEB Corp engineering; NewCon Steel® manufactures the bolted cold-formed steel (AISI S100). Tell us in your inquiry and we'll route you to the right company instead of forcing a solution.
Where there is no qualified welding crew available and no local weld inspection, bolted structure removes the dependency. The skilled work stays in the Panama plant. When a project calls for hot-rolled steel frames, PEB Corp engineering compares the two systems; for the finished building, SmartBrix Construction delivers turnkey steel-framed construction.
Because nothing is welded, the Zn-Al-Mg coating of 275 g/m² applied to the coil reaches the connection intact. A field weld destroys the coating precisely where the structure is most exposed.
Bolted erection is repetitive and measurable: lift, align, torque. There is no field weld inspection interleaved between members and no coating rework waiting at the end.

±0.5 mmNewCon Steel bolted structural steel is not welded on site because every hole and every connection is executed by CNC in the plant, on steel that is already coated. Welding in the field would destroy the metallic coating in the heat-affected zone and force a paint repair that does not reproduce the factory coating. With bolted connections, the Zn-Al-Mg coating of 275 g/m² reaches the connection intact, and the connection is the most exposed point in the structure.
No. NewCon Steel bolted structure is erected by an erection crew: lift, align, torque. It does not require qualified welders, welding equipment, or field weld inspection. This matters most on Caribbean islands and remote sites, where finding and certifying a welding crew is a schedule and cost risk that is rarely in the original budget.
No. NewCon Steel's coating is applied to the originating coil, not in a dip bath after the part is finished. It is a zinc-aluminum-magnesium alloy of 275 g/m² total across both faces, designated ZM275 (EN 10346) / ZMM275 (ASTM A1046 Type 1). There is no batch galvanizing after fabrication and no site galvanizing: the piece comes off the line already coated. At cut edges and punch-outs, the magnesium and aluminum in the alloy form a protective film over the exposed steel.
NewCon Steel bolted structure is cold-formed and designed to AISI S100-16 (R2020) with Supplement 3 (S3-22) and AISI S240-20. Seismic design follows AISI S400-20, loads follow ASCE/SEI 7-22, and verification is run against the code of the destination country.

Yes. NewCon Steel bolted structure combines with LGS structural kits in hybrid systems: the bolted portal frames form the skeleton and the LGS framing handles walls, floors, and roof. Everything is manufactured in the same plant, with the same Zn-Al-Mg coating of 275 g/m² and the same ±0.5 mm tolerance, and it ships on a single purchase order.
