Buying concrete block — what matters
The honest way to judge SEAC Marine Float Block System – Modular Floating Structure Solution is against the job it has to do, not against the cheapest thing that shares its name.
- Specification over price. Two products in concrete block can share a description and be built to very different standards. Check the spec table above before comparing prices.
- Quantity. Order to the drawing plus a realistic allowance. A second delivery usually costs more than the material it carries.
- Lead time. Stock position moves weekly. We confirm availability before you commit, not after.
- Volume pricing. The listed R2.5 is the single-unit rate; ask for a contract rate on quantity.
