Ronsco, Inc., a union carpentry contracting firm in New York, N.Y., provides solutions that small and medium-size general contractors often can’t find from other subcontracting firms.
“The big GCs don’t see us creating a lot of value, because they tend to look at subcontractors as commodities,” says Lee Zaretzky, Ronsco president. “But the small and mid-size contractors appreciate our high level of professionalism and expertise.”
Recently, Ronsco became a Certified Cold-Formed Steel Contractor with the Steel Framing Industry Association (SFIA).
Here are 3 reasons why cold-formed steel (CFS) certification has been a boon to the firm.
1. CFS Certification is a Differentiater
At the time of publication, Ronsco was the only SFIA Certified Contractor serving New York City and the surrounding area.
The SFIA Certification Program for Professional Contractors and Truss Fabricators ensures that GCs choose a firm with experience, expertise and a focus on quality.
“Having cold-formed steel framing certification is one less thing a GC has to worry about,” Zaretzky says. “We use it in our marketing whenever we can.”
2. CFS Certification Establishes Expertise
Zaretzky cites a museum project currently underway in New York City to showcase his firm’s CFS proficiency. The project is an amphitheater with radiused walls.
“The contractor brought us in early to help design, develop and come up with solutions,” Zaretzky says. “Cold-formed steel was one of them.”
Ronsco partnered with a manufacturer that supplies a specialty CFS product. The curved walls weren’t specified to be built using the product. But, by being involved early in the project, Ronsco was able to partner with this manufacturer, which helped design and engineer the curved wall systems.
“In the end,” Zaretzky says, “we offered a cost-effective, better, buildable solution.”
3. CFS Certification Provides Assurance
New York City is unique in being built vertically with lots of building renovation and tenant improvement projects under way. Zaretzky says most projects feature CFS framing.
“We convert the framing on many projects to cold-formed steel, a more cost-effective, non-combustible solution than combustible wood framing,” Zaretzky says.
He adds: “Even the old wood buildings are being converted over to steel joists whenever possible. In many instances, we’re able to provide a cold-formed steel solution when higher cost ‘red’ steel is specified.”
SFIA Certification helps Ronsco’s customers appreciate such recommendations.
“Knowing that a contractor had to meet certain criteria — and supply evidence of cold-formed steel education and proficiency — provides comfort to our customers,” Zaretzky says.
