Our story
Our History
The iterations of the company that would eventually become G P Roadway Solutions began in 1978, when Sidney Quintal purchased Safety Equipment and Sign Co. Over the years the company expanded its services to material sales and barricade rentals, servicing Hawaii's burgeoning construction industry.
By 1980, the company acquired the full line of Unistrut products for material sales. By 1991, all activities were conducted by three distinct companies: Safety Equipment and Sign Co., Unistrut Hawaii, and National Barricade. Together, they made up SUN Industries Inc. In 2002, SUN Industries Inc. acquired custom sign company Peterson Sign Company.
In 2003, SUN Industries Inc. was acquired by Grace Pacific, and was rebranded as G P Roadway Solutions to reflect its “G P” affiliation. Grace Pacific Corporation was changed to Grace Pacific LLC.
Today, G P Roadway Solutions services the state of Hawaii with sales and rentals of safety equipment, custom signage, metal framing and grating systems, and maintenance services.
