Components Maker A.L.P. Acquired by Inteplast
ALP Lighting Components now operates within Inteplast’s Sustainable Packaging & Printing Solutions division
A.L.P., the Niles, Ill.-based maker of LexaLite optics and Steel Craft fixture kits, has been acquired by Inteplast Group, a privately held plastics and paper manufacturer. Bill Brown Sales, the OEM component agency where the Brown family business began in 1955, is not part of the deal and will continue as ALP’s sales representative.
In 1972, Carolite told Bill Brown it didn’t want him as a rep, worried that his reach across much of the country would conflict with its other agencies. Carolite offered instead to make products he could sell under private label, which required a separate distributorship. That distributorship became A.L.P. Fifty-four years later, it has a new owner.
Same Plants, Same Management, Same Rep
ALP will operate as ALP Lighting Components LLC, an Inteplast Group company, within Inteplast’s Sustainable Packaging & Printing Solutions division. Terms were not disclosed. Adam Mayse remains president and chief operating officer, and the company said its manufacturing facilities, customer service and technical teams stay in place. CEO Steve Brown will support ALP’s lighting growth alongside Bill Brown Sales. Mayse said OEMs can expect continued access to the engineering, manufacturing and technical support they rely on, now with more resources behind it.
Steve Brown described the deal as the end of “more than 70 years of family ownership.” That figure dates to the founding of Bill Brown Sales; ALP itself had been family-owned since 1972. Bill Brown passed away in 2024.
The footprint is unchanged. Niles is headquarters, housing executive offices, customer service and Midwest warehousing. The plants are in Charlevoix, Mich., which makes the LexaLite prismatic Reflexor and indoor and outdoor lenses; Dickson, Tenn., an injection-molding plant with 180- to 1,500-ton presses; and Apodaca, outside Monterrey, Mexico, which produces gasketed enclosures, aluminum louvers and baffles. A distribution center operates in Lithia Springs, Ga.
Optics, Kits and a Steady Narrowing
ALP now goes to market under two brands. LexaLite handles proprietary and custom injection molding in optical acrylic, polycarbonate and silicone. Steel Craft supplies component kits for lighting and other segments. The featured product is the S22 Reflexor, a shallow-profile optic built for LED high bays, and ALP also sells by application, from DesignLights Consortium (DLC) fixture kits and horticulture to roadway and parking garage lighting.
The company got here by adding and subtracting. Its purchase of Spectrus brought in LexaLite, and in 2018 it sold its extrusion business, saying the move would let it focus on and invest in injection-molded optics.
A Lighting Supplier in a Packaging Division
Inteplast is headquartered in Livingston, N.J., with its flagship manufacturing complex in Lolita, Texas, and says it has more than 10,000 employees and over 100 facilities worldwide. It has been a steady acquirer; last year it bought con-pearl, a German maker of polypropylene board, which joined its World-Pak division. ALP’s new division includes Profile in Lolita, Coroplast in Vanceburg, Ky., and CoolSeal in Perrysburg, Ohio.
An optical molder filed under packaging and printing is an unusual org-chart choice, and one worth a follow-up, since the announcement doesn’t explain the placement. It does say what Inteplast valued: ALP’s optical molding expertise and its Mexico operations. Lighting remains a core focus, the company said, with expansion into other markets supporting investment in capabilities that benefit lighting manufacturers.
