Company History

StressCrete Ltd., a utility pole manufacturer, is founded. The company manufactures static cast tapered square poles that are considered upgrades from standard wood.


Manufacturing of the original poles ceases when the company invests in spinning technology, which not only enables them to produce a round cross section, but also vastly improves the strength and durability of the product. This transition also enables the company to expand into the regional market, manufacturing product for Southern Ontario and the state of Michigan. The product line grows to include power distribution, sub-station structures, hi-mast, sports lighting and strain poles, as well as the original lighting poles.


StressCrete Ltd. purchases Barratt Spun Concrete Poles, a company with a more decorative line of lighting poles, primarily servicing the U.S. market. Recognizing the growth movement toward traditional and historic outdoor lighting, StressCrete Ltd. designs and purchases molds that enable them to supply this demand.


StressCrete Ltd. acquires ornamental luminaire manufacturer King Luminaire Co. Inc., which is currently based in Jefferson, Ohio, to offer a complete lighting package. This substantially increases the company's rate of growth, positioning the company as a full service industry leader.

King Luminaire Co. Inc. adds a Highly Accelerated Life Testing (HALT) system to the technical center at its Jefferson, Ohio facility. The HALT system allows King Luminaire Co. Inc. to analyze and improve the reliability of their product by subjecting product samples to extreme operational stress. The repeated application of these stresses (heat/cold, humidity, and vibration) enables King Luminaire Co. Inc. to analyze and improve product design and manufacturing processes. This substantial investment helps them continue to produce the highest quality products in their industry.


King Luminaire Co. Inc. completes a 53,000 square foot expansion of its Jefferson, Ohio facility. This multi-million dollar investment offers a new state-of-the-art Surface-Mount Technology (SMT) system and center, added space for continued product assembly, as well as an expansion of both their technology center and quality control area. This investment allows them to continue their path of new product development and obtain growth objectives for years to come.
