Features
Vanstone developed square and rectangular Concrete Replacement Covers as a solution to the scourge of stolen cast iron covers. Cast iron fetches a high price for its scrap-metal value and is stolen freely.
Vanstone’s Replacement Covers are unique and have the following features:
- Drop it directly into the old built-in cast iron frame without any adjustments or reconstruction necessary. It fits snugly and the top surface is flush with that of the frame.
- It has the same load bearing capacity as the cast iron cover that it replaces..
- Made of concrete with only some mild steel visible. Furthermore it is heavy. This makes it unattractive for removing and selling.
- All steel including reinforcing is hot dipped galvanized.
Construction
- High Strength reinforced concrete with a steel rim for protection against chipping and wheel scoffing.
- All steel components including the reinforcing is hot dipped galvanized.
- Two lifting holes.
Applications
Direct Replacement
The Vanstone Replacent Covers are made of high strength concrete and steel but little of the steel is visible. It is also obvious that the steel is not cast iron but ordinary mild steel. The Concrete Covers are heavy and weigh at least 50kg. It is not easy to lift and carry away. To remove the steel from the concrete by chopping by hand or machine is labourious and time consuming. The whole thing is just not worth it.
The Vanstone Replacement Covers can be dropped directly into the old cast iron frame. As long as it is a standard frame made to the old SABS code, it will fit perfectly. The top is flush with the top of the frame and does not protrude. It can therefore be used safely within any paved surface and will not cause an obstruction. Normally no adjustment, breaking, replacement of frame or building work is necessary.
Load Bearing Capacity
The Vanstone’s Replacement Covers were developed to replace traditional cast iron covers of the same code. The new Concrete Covers are strong enough to do the same work as the old cast iron covers that it will replace.
Edge protection against brittle failure and chipping is by means of a mild steel lining. All steel parts in the Cover including reinforcing steel is fully hot dipped galvanized.
