Cantilever Base
Overview
- Made by
- Supply chain / partners
- Materials
- Steel plate base with cast inserts, Concrete-filled resin base, Granite or marble block with steel plate
- Finish options
- Powder-coated steel, Textured resin, Polished stone
Selection tips
- Base mass has to match the canopy footprint and the wind zone; calculate overturning rather than quoting a kilogram figure.
- Stone bases look premium but ship heavy and crack; water or sand-filled plastic bases are cheap but seep and lose mass over time.
- Weld the plate base then protect the inside: unpainted internal walls rust through from the inside out.
- Against a spike or sand anchor: heavy bases suit commercial terraces, while grass and sand need a spike or auger, not more weight.
Manufacturing process & quality control points
- 1
Plate cutting and forming
Supply chain / partnersSteel plate is cut, formed and welded by the supply chain. A cantilever base works in overturning, not compression, so plate area and weld quality matter more than sheer weight.
Quality control points
- Plate dimensions and weld · Tape measure + visual weld check per drawing · First article + 1 pc per 2 h
- 2
Filling or stone fitting
Supply chain / partnersResin bases are filled with concrete; stone bases are drilled and fitted with the steel plate. Filling weight is checked, because an underweight base overturns.
Quality control points
- Base mass · Weigh each base or a defined sample · Per batch
- 3
Surface finishing
Supply chain / partnersCoating is applied by the supply chain and checked for corrosion; the base sits on wet ground permanently.
Quality control points
- Coating thickness and corrosion · Thickness gauge; neutral salt spray (ISO 9227 / GB/T 10125) · Per batch
- 4
Overturning check
Supply chain / partnersThe base is checked against the agreed overturning requirement with the arm fully extended. This is the safety-critical test on a cantilever parasol.
Quality control points
- Overturning resistance · Apply the agreed load or wind simulation with the arm extended, no overturn · Per order
