Key Products/TechnologiesKeyProducts/Technologies
TG DECK (Integrated Deck Plate): A product integrating truss girders assembled with high-yield strength deformed steel bars and a 0.5mm thick galvanized steel plate through fold-welding. Designed to prevent corrosion of the lower part by not exposing the steel plate after concrete pouring, and ensures high productivity and structural strength precision through automated PITCH adjustment facilities.TGDECK(IntegratedDeckPlate):Aproductintegratingtrussgirdersassembledwithhigh-yieldstrengthdeformedsteelbarsanda0.5mmthickgalvanizedsteelplatethroughfold-welding.Designedtopreventcorrosionofthelowerpartbynotexposingthesteelplateafterconcretepouring,andensureshighproductivityandstructuralstrengthprecisionthroughautomatedPITCHadjustmentfacilities.
GREEN DECK (Demountable Deck Plate): A product allowing reuse of the lower steel plate through bolt-assembly.GREENDECK(DemountableDeckPlate):Aproductallowingreuseofthelowersteelplatethroughbolt-assembly.
HEAT DECK (Insulation-integrated Deck Plate): A new product featuring excellent polyurethane insulation material attached to the underside of the deck plate. Key advantages include reduced construction time by eliminating insulation processes, superior insulation performance (energy saving) due to seamless installation, and cost savings compared to post-insulation methods. Available in various specifications for slab thicknesses from 120mm to 300mm and insulation thicknesses from 50mm to 200mm.HEATDECK(Insulation-integratedDeckPlate):Anewproductfeaturingexcellentpolyurethaneinsulationmaterialattachedtotheundersideofthedeckplate.Keyadvantagesincludereducedconstructiontimebyeliminatinginsulationprocesses,superiorinsulationperformance(energysaving)duetoseamlessinstallation,andcostsavingscomparedtopost-insulationmethods.Availableinvariousspecificationsforslabthicknessesfrom120mmto300mmandinsulationthicknessesfrom50mmto200mm.
FLOOR SOUND INSULATION (Floor Soundproofing Material): Known as the 'SY Sonics U System,' composed of soundproofing, sound-absorbing, and vibration-damping materials. Features soundproofing material with excellent compressive strength, waterproofing, and sound insulation from hollow plastic sheets, high-density fiber sound-absorbing material with superior sound absorption and insulation, and special anti-vibration rubber with semi-permanent anti-aging and recovery properties. Performance verified in LH sites.FLOORSOUNDINSULATION(FloorSoundproofingMaterial):Knownasthe'SYSonicsUSystem,'composedofsoundproofing,sound-absorbing,andvibration-dampingmaterials.Featuressoundproofingmaterialwithexcellentcompressivestrength,waterproofing,andsoundinsulationfromhollowplasticsheets,high-densityfibersound-absorbingmaterialwithsuperiorsoundabsorptionandinsulation,andspecialanti-vibrationrubberwithsemi-permanentanti-agingandrecoveryproperties.PerformanceverifiedinLHsites.
