Grătarul de bare rezistente este sudat prin rezistență pentru a asigura rezistență, durabilitate și siguranță maxime. Și poate rezista la sarcini grele în mod repetat. Oferim grătare rezistente din oțel carbon și grătare rezistente din oțel inoxidabil pentru a satisface nevoile clienților. Grilajul rezistent este considerat a fi grile ideale pentru zonele grele, cum ar fi autostrăzi, parcări, docuri de încărcare, rampe, aeroporturi, terminale de camioane și autobuze, autobuze, stații de marfă, metrouri și fabrici industriale.
Specificația este după cum urmează:
* Lățimi standard: 2′, 3′ și 4′ în lungimi de 20′.
* Bare de rulment standard: 1/4″, 5/16″ și 3/8″ grosime.
* Barele variază de la 1″ la 8″ adâncime.
Caracteristici principale
* Capacitate portantă mare
* Bună rezistență la alunecare
* Ușor de instalat și îndepărtat
* Diverse tratamente de suprafață
Aplicații
* Protecția mașinilor – Poate fi folosită pentru a proteja mașinile de a fi deteriorate de obiectele care cădeau.
* Grile de ventilație – Asigurați fluxul lin al aerului.
* Treptele scărilor – Oferă o bună rezistență la alunecare.
* Garduri – Protejați oamenii și proprietățile de a fi deteriorate de căderea obiectelor.
* Balustrade – Capacitate portantă bună și pot fi folosite ca balustrade.
