Ordering instructions:

When placing an order, please specify in detail the model, specifications, installation and structural form, as well as the distance H from the center of the door to the platform.

2. Our company's series of gates have a positive pressure head of ≤ 10m. If this head is exceeded, special orders are required. When both sides of the gate are subjected to water pressure and the reverse head is greater than 3m, please choose a bidirectional gate, which must be installed in a wall mounted manner, with the same embedded parts as the unidirectional gate, but for G less than 120, it should be taken as 120.

3. The gate body and door frame materials are generally made of gray cast iron. If ductile iron gates or stainless steel welded gates are required, please specify.

4. The anchor bolts shall be provided by the user, please indicate if necessary.

5. In order to better serve users, our company can provide detailed drawings of embedded parts for non-standard gate specifications.
