With our attention to detail, fully automated facilities and processes, unsurpassed customer service, and the best employees, Linetec is recognized as the most reliable, highest service and best quality finisher in the industry. This Linetec facility tour showcases both our paint and anodize facilities.
90-degree thermal strut in a single step
“Linetec is one of very few companies in North America to provide 90-degree thermal strip with a single pass using Technoform Bautec’s polyamide insulating strips and Müller Technologies AG’s knurling equipment to install the strip simultaneously on two planes of material,” explains Bart Hensley, sales engineer at Technoform Bautec.
The need for direct access from both sides has always been a design limitation of strip systems. This new capability frees up window and curtainwall designers to detail changes in place more efficiently, using a single assembly, rather than multiple pieces – without compromising energy efficiency or condensation resistance.
When installing thermal strip, Linetec follows the requirements of AAMA QAG-2-12, “Voluntary Quality Assurance Processing Guide for Polyamide Thermal Barriers.” First, the inside and outside aluminum profiles are finished in anodize, liquid paint or powder coating. Different colors and finishes may be used on each profile as the aluminum is extruded independently with a cavity that will receive the strip.
During the assembly process, knurling produces “teeth” in the aluminum pocket that “bite” into the strip and ensures appropriate shear strength of the composite profile. As material passes through the knurler, the strip is inserted into the extrusion cavity. The crimping process mechanically locks the aluminum and strip, forming the bond between the two extrusions and the strip.
Traditional 90-degree thermal strip installation was time-consuming where each piece is knurled up to three times before crimping and shear testing. This amount of handling increases the potential for marring and damage to the finished material. This new 90-degree thermal strip process employed by Linetec’s reduces the knurling to one step. This not only saves time and labor, but also minimizes inconsistencies and waste, holds customer-specified tolerances for U-Factor and shear testing, and delivers a high-quality finished product.
Aluminum finishing, curving and thermal improvement services all provided at a single location
As building projects continue to push the limits in vision and design, Linetec continues to expand its value-added services. Linetec will soon offer stretch forming, which allows architectural product manufactures to have their metal building components curved and finished in one location.
“Customers needing material to be curved can send the parts to Linetec or have it pulled from their material stored and managed in Linetec’s inventory program. This offers customers quick-turn bending services. Utilizing the company’s dedicated fleet of trucks ensures the finished, curved material, along with the rest of the project, arrives free from damage, on schedule and backed with an industry-leading warranty
Stretch Forming by Linetec alleviates the worry and hassle of multiple points of contact and brings tremendous value. Customers can ship us their aluminum for bending and then, have it finished in the same place to retain the full finish warranty. This saves shipping costs and transit time, as well as reduces material handling and packaging to minimize the opportunity for damage.
To deliver the new stretch forming services, Linetec has teamed with Southern Stretch Forming. Southern Stretch is headquartered in Texas with production facilities in California and Pennsylvania. The company will provide a full scope of bending capabilities on Linetec’s campus in Wausau, Wis., including annealing and tempering to soften and harden aluminum. Facility site preparation, equipment deployment and other logistics are underway.
When we realized stretch forming would be of benefit to customers, we sought out a partner with an equal reputation in their industry; a quality company with a strong reputation for customer service and reliability. We are glad to have Southern Stretch Forming as that partner.”
Southern Stretch Forming’s president, David Arthur, notes that the feeling is mutual, “We have very high regard for Linetec and are pleased to have established a strong collaborative relationship with their team.”
Arthur explains, “In simplest terms, stretch forming is a way of bending metal into a desired shape, usually curved, by heat treating it then pressing it over a die. Stretch forming turns a straight aluminum extrusion into a vital component of contemporary structures — a hotel skylight, a mall archway or a skyscraper’s glass and metal facing. Stretch forming frees architects, designers and builders to realize forms as graceful as they are sturdy and functional.”
Expanding services to enhance architectural metal components is nothing new to Linetec. We continually invest in these innovative, value-added services to support our customers’ short-term needs and long-term goals.

Due to Linetec’s recent anodize facility expansion, 75th Avenue has become part of Linetec’s property and is no longer a city street. This means our mailing address must change.
Linetec’s official mailing address is now 7500 W. Stewart Avenue, Wausau WI 54401. The post office will continue to deliver mail that has our old address on it for up to 18 months and will also recognize the new address immediately. We have updated the majority of paperwork, invoices, and our systems.
The address for the Polywood Paint facility is 7200 W Stewart, Wausau WI 54401 and the Anodize address is 7550 W. Stewart, Wausau WI 54401. These identify the buildings but should not be used for mailing address purposes (mail will not be delivered to these locations). All mail should be sent to Linetec’s main address 7500 W Stewart Avenue, Wausau WI 54401.
Please note that there is no change to our payment remittance address.
Class I and Class II anodic coatings are designations created by the Aluminum Association for the purpose of codifying the specification of anodized aluminum.
Class I coating has a mil thickness of 0.7 (18 microns) or greater
Class II coating has a minimum mil thickness of 0.4 (10 microns)
Class I coating is a high performance anodic finish used primarily for exterior building products and other products that must withstand continuous outdoor exposure.
Class II coating is a commercial anodic finish recommended for interior applications or light exterior applications receiving regularly scheduled cleaning and maintenance such as storefronts.
Class I and Class II coatings should not be confused with Type I, Type II, and Type III anodic coatings as described in the authoritative anodizing standard, MIL-A-8625. Type I anodize refers to chromic acid anodizing. Type II is normal “clear” sulfuric acid anodizing. Type III is “hardcoat” using sulfuric acid or mixed chemistry electrolytes.
All Linetec anodize finishes are produced as a Class I coating, with the exception of ANO-204 Clear, which is a Class II coating. Clear anodize is available in both Class I and Class II.
Class II anodic coatings are recommended for interior applications or light exterior applications receiving regularly scheduled cleaning and maintenance such as storefronts and entrance ways. Class II anodize is not as durable or wear resistant as a Class I finish.
Class I anodic coating is a high-performance finish used for exterior building structures and other products that must withstand continuous outdoor exposure. Class I anodize is more resistant to salt spray and the sea coast, and it is more durable in high traffic areas.
At Linetec, we are building a 30,000-square-foot addition to the anodize facility in Wausau, Wis. To support the addition and growth of business, we also are increasing the anodize staff by more than 10 percent.
By January 2014, a 33 percent increase in capacity for anodize finishing of architectural aluminum will be on-line and available.
“We’re as busy as we’ve ever been,” said Linetec’s president, Rick Marshall. “This is the sixth building expansion in the past 10 years. We continue to grow and serve our customers with the quality and reliability that they’ve come to expect from Linetec.”
He continued, “Supporting our growth in capacity, we’re growing our staff, too. Not only are we filling the additional jobs due to our anodize expansion, but we’re also bringing on more people to meet the all-around increased demand for our finishing services.”
Construction of Linetec’s anodize facility addition began in August and will be completed by the end of October. “We plan to be up and running before November. Along with extra capacity, the extra space gives us the opportunity to increase efficiency by streamlining our process, improving the workflow and enhancing productivity,” noted Andy Joswiak, Linetec’s vice president of operations.
Jon Close, Linetec’s vice president of sales, added, “We also are increasing our warehousing capacity to provide more room for our Linetec Managed Inventory program. This further benefits our customers by keeping their material on hand and providing just-in-time finishing; whatever they need, whenever they need it.”
In addition to expanding its capacity, Linetec also expanded its geographic reach. Earlier this year, we added more service and distribution routes, including our first regular route to Toronto, Canada.
Linetec, Wausau Window and Wall Systems and Technoform Bautec North America, Inc., contribute to the updated appearance and enhanced performance of historic Houghton Academy in Buffalo, N.Y. Along with refreshed façade, the elementary school’s modern windows feature Technoform Bautec’s polyamide thermal barrier for energy efficiency, structural performance and long-term durability.
Glazing contractor T.G.R. Enterprises replaced 125 of the building’s outdated windows with Wausau Window and Wall Systems’ high-performance units. These windows were finished by Linetec and customized to match the elementary school’s architectural aesthetic using a Sandstone color paint on the exterior and a Dark Bronze anodize on the interior.
Constructed in 1924, Buffalo Public School #69 Houghton Academy was designed by the Associated Buffalo Architects Inc. The U-shaped floor plan surrounds a courtyard in the rear and a Classic Revival style entrance in the front. The brick and stone structure is punctuated with large window bays. As time passed, the windows were replaced without preserving the architectural integrity. This resulted in inconsistent window types, trim and colors.
“Choosing different color schemes and finish types for the interior and exterior of a high-performance aluminum window system can be achieved within budget and on accelerated timelines,” says Chad Ricker with Technoform Bautec’s market team. “Because two different finishing types were used on Houghton Academy windows — paint and anodize, any other thermal barrier method would not have been an option for this project.”
To ensure a successful result, the glazing team relied on Wausau’s 310i Series single-hung and 4250i-XLT INvent™ Series project-out windows. Both are manufactured using Technoform Bautec’s polyamide thermal barriers, known generically as “thermal strip.”
For two-color frame finishing using paint at the interior and exterior, Linetec estimates that Technoform Bautec’s thermal strip system painted assemblies are 400% less expensive than other thermal barrier methods that require time-consuming masking. read more
