FIELD: building materials.
SUBSTANCE: group of inventions relates to a structural support made with the possibility of relative movement between parts of a building structure, usually progressive and/or rotational movement, and its manufacturing method. Structural support (1) includes first part (2) of the support forming at least one limiting cavity (4, 4'); second part (6) of the support located at least partially in front of limiting cavity (4, 4'); and sliding element (8) placed in limiting cavity (4, 4') and located between first part (2) and second part (6) of the support. Sliding element (8) consists of heat-treated fluoropolymer with a melt flow rate (MFR) by weight of less than 5.0 g/10 min.
EFFECT: increase in the compression strength of the sliding element of the support, resistance to chemicals and significant inertia to atmospheric effects.
