Galvanized pipes https://www.veskr.com.ua/novosti-v-ukraine/73575-preimushchestva-otsinkovanykh-trub.html can withstand any temperature or humidity changes. Regular black metal pipes are used as a base for galvanizing. The coating can be external only or in combination with internal. High strength indicators allow them to be used in conditions of mobile soils - they are not afraid of deformation or mechanical impact on bending. Unlike regular pipes, galvanizing can be produced not only with a round, but also with a square or rectangular cross-section and to order.
