Diverse Range of Municipal Castings for Airports and Ports
Manhole Covers
We manufacture grey cast iron and ductile iron manhole riser rings / extension rings / repaving rings / paving riser rings as well as fabricated mild steel riser rings. All the products are available in ASTM A48 Class 35B. Steel Riser rings are made of ASTM A36 steel and galvanized as per ASTM A123 (if required). Fabricated Mild Steel Riser Rings are specially designed to allow for small variances in Manhole Rings.
Solid top multileaf Covers:
We manufacture Solid Top Multi Leaf Covers that offer versatile solutions for covering large pit sizes. Featuring hinged, lightweight designs, they are easy to handle and can be removed from the frame as needed, ensuring convenient access and maintenance.
Gas & airtight inspection covers:
Gas & airtight Inspection Covers are essential for odour control and water leakage prevention. Ideal for sewerage and cable duct lines near buildings, these recessed covers integrate seamlessly with surroundings for a refined aesthetic appearance and enhanced safety.
Channel & Gully Gratings:
We offer a wide range of Linear Gratings used for drainage of stormwater. Item set consists of a Grate and two rails on both sides as standard design. The gratings are available in a range of profiles to suit different applications, and can be custom made to suit your specification.
Access Hatches:
These are formed from Galvanized Mild Steel Plate as standard. They are designed to sit in a preformed recess, making our Hatch flush with the floor surface. The hinged, self-locking grid provides an extended handhold for safe ladder decent when in the open position, which can be used during emergency. The grid also acts as a physical barrier to prevent accidental lid closure when open. The Covers are spring loaded and can be opened from inside as well as outside and can be latched.
