ApATeCh | Structural glass-fiber "SPPS"

«Pultrusion Profile glass-fiber Plastic for Construction Purposes» (SPPS) is a material consisting of glass fiber impregnated with thermosetting resin and designed for the use in civil engineering instead of traditional materials (steel, reinforced concrete, wood).

Climatic tests (Laboratory of STC "SMСМ" of the JSC TsNIIS, 2005)

Frost-resistance according to GOST 10060-95 «Frost-resistance concrete test».

20 and 37 cycles at –55 — +18ºС in 5% solution of NaCl have not revealed reduction of strength.
