摘要： A method of producing a plate-like construction having a double-wall structure and its use. According to the present invention, several elongated profiles which have essentially straight central axes are arranged against each other in such a way that adjacent hollow profiles abut each other and together form, in general terms, a flat stack having two opposite sides. The hollow profiles are welded together in order to join them with welded seams, in which case the welding is essentially carried out simultaneously from both sides of the stack. Besides good flexural strength and the opportunity to recycle, thermoplastic plates which are produced by means of the present method exhibit resistance to corrosion, decay and mould.
