Industry, highly developed in Belgium, is devoted mainly to the processing of imported raw materials into semifinished and finished products, most of which are then exported. Industry accounted for 24% of GDP in 2001. Steel production is the single most important sector of industry, with Belgium ranking high among world producers of iron and steel. However, it must import all its iron ore, which comes principally from Brazil, West Africa, and Venezuela. About four-fifths of Belgium's steel products and more than three-quarters of its crude steel output are exported. In recent years, Belgian industry has been hampered by high labor costs, aging plant facilities, and a shrinking market for its products. Nevertheless, industrial production rose by nearly 11% between 1987 and 1991, as a result of falling energy costs (after 1985) and financial costs, and only a moderate rise in wage costs. Industrial production continued to rise in the late 1990s; 1997 registered a 4% growth rate, while it slowed to3.1% in 1998. The industrial growth rate in 2000 was 5.3%; it was -0.5% in 2001, and registered an estimated 0.6% in 2002.
Production of crude steel declined from 16.2 million tons in 1974 to 11.3 million tons in 1991, while the output of finished steel dropped from 12.2 million tons to 8.98 million. By 1981, 60% of all Belgian steel production and 80% of all Wallonian steel (concentrated in Charleroi and Liège) came under the control of a single company, the government-owned Cockerill-Sambre. Plans for this firm, whose government subsidies ended (in conformity with EC policy) in 1985, called for heavy investment in plant modernization, coupled with cutbacks in employment and plant capacity.
In 1998, Belgium produced 342,000 tons of crude copper. The country also produces significant amounts of crude zinc, and crude lead. The bulk of metal manufactures consists of heavy machinery, structural steelwork, and industrial equipment. The railroad equipment industry supplies one of the most extensive railroad systems in Europe. The automotive industry is strong: Belgium produced 1,187,257 automobiles in 2001, a 15% increase over 2000. It also manufactured 30,499 heavy trucks in 2000, an increase of 20% over 1999. An important shipbuilding industry is centered in Temse, south of Antwerp. Belgian engineering and construction firms have built steel plants, chemical works, power stations, port facilities, and office buildings throughout the world.
The textile industry, dating from the Middle Ages, produces cottons, woolens, linens, and synthetic fibers. In 1991, spinning industry production (including cotton, wool, linen, and jute) totaled 172,329 tons of yarn, and the weaving industry produced 520,616 tons of fabric. With the exception of flax, all raw materials are imported. Centers of the textile industry are Bruges, Brussels, Verviers, Ghent, Courtrai (Kortrijk), and Malines (Mechelen). Carpets are made in large quantities at Saint-Nicolas (Sint-Niklaas). Brussels and Bruges are noted for fine linen and lace.
