I need to replace a corroded steel manhole cover which is beginning to split and is no longer safe to stand on. The frame has rotted, too. The dimensions - lid only. not the frame - are 620mm x 470mm but the only ones I can find listed on the net by Wickes, B&Q et al are all 600 x 450. Are these just nominal dimensions, or am I really looking for a non-standard size? If so, can anyone recommend a supplier?
