Hollow fence accessories should be specified through their decorative shape and mounting geometry. This OEM/ODM aluminum-alloy enquiry includes gravity- or sand-casting requests and CNC precision machining. For a hollow accessory, the visible exterior and the mounting faces can require different delivered conditions. Describe both so the requested finish is assessed alongside the geometry.
Define the hollow geometry and fence connection
Provide the component drawing with the internal and external geometry required by the design. Show how the accessory connects to the fence or associated assembly. Identify the aluminum grade and the interfaces needing finished dimensions.
- Supply the accessory drawing and selected alloy.
- Describe the hollow shape and mounting requirements.
- Identify gravity- or sand-casting scope.
- Mark CNC interfaces and tolerance limits.
- Select the surface treatment and appearance.
- State quantity and inspection requirements.
Select the finish for functional and visible areas
Sandblasting, painting and polishing are named choices. Describe the required result and any mounting areas needing particular finishing instructions. The selected treatment should be included with the finished-part acceptance rather than inferred from a general fence-accessory description.
Specify the applicable material and supplier documents
GB, ASTM, AISI, DIN and BS are named standard families. Identify the document and grade that apply to the ordered aluminum component. ISO9001:2015 is the qualification reference for which applicable current documents and scope should be requested. The geometry, machining and finish requirements should establish the actual accessory without an assumed weather-resistance or structural-load rating.
