we also supply electrical wire harnesses , control panels , electro-mechanical and cable assemblies , seating systems and other products to automotive , military , bus , agriculture , transportation , mining , industrial and off-road recreational markets . we have manufacturing operations in the united states , mexico , china , united kingdom , czech republic , ukraine , thailand , india and australia . our products are primarily sold in north america , europe , and the asia-pacific region . we are differentiated from automotive industry suppliers by our ability to manufacture low volume , customized products on a sequenced basis to meet the requirements of our customers . we believe our products are used by a majority of the north american md/hd truck and many medium- and heavy-duty construction vehicle original equipment manufacturers ( “ oems ” ) , and to a lesser extent other makers of industrial equipment . in the quarter ended december 31 , 2018 , we completed a strategic reorganization of our operations into two business segments , electrical systems and global seating . the reorganization allows the company to better focus its business along product lines , as opposed to end markets , which the company believes enhances the effectiveness of seeking out growth opportunities and shareholder value . business overview for the year ended december 31 , 2019 , approximately 49 % of our revenue was generated from sales to north american md/hd truck oems . our remaining revenue was primarily derived from sales to oems in the global construction equipment market , aftermarket and oe service organizations , military market and specialty markets . demand for our products may be driven by preferences of the end-user of the vehicle , particularly with respect to heavy-duty trucks . unlike the automotive industry , heavy-duty truck oems generally afford the end-user the ability to specify many of the component parts that will be used to manufacture the vehicle , including a wide variety of cab interior styles and colors , brand and type of seats , type of seat fabric and color , and interior styling . certain of our products are only utilized in heavy-duty trucks , such as our storage systems , sleeper boxes and privacy curtains . to the extent that demand for higher content vehicles increases or decreases , our revenues and gross profit will be impacted positively or negatively . we generally compete for new business at the beginning of the development of a new vehicle platform and upon the redesign of existing programs . new platform development generally begins one to three years before the marketing of such models by our customers . contract durations for commercial vehicle products generally extend for the entire life of the platform . several of the major truck makers have upgraded their truck platforms and we believe we have maintained our share of content in these platforms . we continue to pursue opportunities to expand our content . demand for our heavy-duty ( or `` class 8 `` ) truck products is generally dependent on the number of new heavy-duty trucks manufactured in north america , which in turn is a function of general economic conditions , interest rates , changes in government regulations , consumer spending , fuel costs , freight costs , fleet operators ' financial health and access to capital , used truck prices and our customers ' inventory levels . new heavy-duty truck demand has historically been cyclical and is particularly sensitive to the industrial sector of the economy , which generates a significant portion of the freight tonnage hauled by commercial vehicles . north american heavy-duty truck production was 342,000 units in 2019. according to a february 2020 report by act research , a publisher of industry market research , north american class 8 production levels are expected to decrease to 225,000 units in 2020 , steadily increase to 340,000 units in 2023 and then decline to 246,000 units in 2024. act research estimated that the average age of active north american class 8 trucks was 6.4 and 6.6 years in 2019 and 2018 , respectively . as vehicles age , maintenance costs typically increase . act research forecasts that the vehicle age will decline as aging fleets are replaced . 35 north american medium-duty ( or `` class 5-7 `` ) truck production steadily increased from 249,000 units in 2017 to 281,000 units in 2019 . according to a february 2020 report by act research , north american class 5-7 truck production is expected to decrease to 249,000 units in 2020 , steadily increase to 274,000 units in 2023 and then decline to 268,000 units in 2024. we primarily participate in the class 6 and 7 portion of the medium-duty truck market . demand for our construction equipment products is dependent on vehicle production . demand for new vehicles in the global construction equipment market generally follows certain economic conditions around the world . our products are primarily used in the medium- and heavy-duty construction equipment markets ( vehicles weighing over 12 metric tons ) . demand in the medium- and heavy-duty construction equipment market is typically related to the level of large scale infrastructure development projects , such as highways , dams , harbors , hospitals , airports and industrial development , as well as activity in the mining , forestry and commodities industries . the construction markets we serve in north america , europe and asia have declined . story_separator_special_tag moreover ,
