Slotted Top Rail Systems are selected for glass layouts requiring a slotted rectangular upper rail. A slotted rectangular top rail fits over the glass edge through a matching insert, forming the specified upper rail line. Confirm the geometry against the complete layout before choosing components.
Hengke Casting can review required certification documentation for the specified components. Confirm the applicable requirements and supporting records before ordering.
| System layout Slotted Top Rail Systems
| A slotted rectangular top rail fits over the glass edge through a matching insert, forming the specified upper rail line. Upper glass edge aligned inside the rail slot Slotted top profile and compatible glass-edge insert Confirm the top edge and end termination. Specify the required appearance. |
| Connection review | Check rail section, slot opening, insert profile, junctions and end termination. Match glass thickness and insert dimensions. Identify the supporting construction. Confirm the complete component list. |
| Project dimensions | Panel lengths and heights Post or profile positions Junction angles Glass edge clearances Mounting hole positions Finish levels and offsets Access for fitting and maintenance |
| Finish specification | State the required surface appearance. Provide a colour or finish reference. Identify all exposed faces. Confirm available options for the selected components. Keep the approved finish recorded for repeat orders. |
| Product geometry | A slotted rectangular top rail fits over the glass edge through a matching insert, forming the specified upper rail line. |
| Dimensions to confirm | Connection details: Upper glass edge aligned inside the rail slot. |
| Mounting details: Slotted top profile and compatible glass-edge insert. | |
| Critical dimensions: rail section, slot opening, insert profile, junctions and end termination. | |
| Glass data: thickness, panel size, edge preparation and insert compatibility. | |
| Material review | State the required alloy for each metal component. Request confirmation against the selected drawing. |
| Identify material documentation required for the project. Confirm the insert and fixing materials separately. | |
| Appearance alone does not establish alloy grade. | |
| Layout information | Straight-run dimensions Stair or ramp positions where applicable Corners and changes in direction Start and end conditions Wall connections if required Supporting slab or other substrate Top rail continuity and joints Access around the installation Delivery grouping by marked position |
| Drawings | Supply a dimensioned plan, elevations and connection details for the actual installation. |
| Project requirements | Identify the applicable project requirements and the documents needed before selecting the complete assembly. |
| Review checklist | Selected component version Dimensions and interfaces Material specification Surface finish reference Included and separately sourced components Project-specific suitability review Agreed supply and delivery scope |
Specify this arrangement from a dimensioned layout showing the glass, supporting construction and adjacent junctions. Record rail section, slot opening, insert profile, junctions and end termination, together with the glass thickness and edge preparation. Confirm how the selected component interfaces with neighbouring parts.
Hengke Casting can review an enquiry that identifies the required material, appearance and supplied component list. Ask for confirmation of the proposed version and any documentation needed for the project. Installation examples illustrate a layout and are not presented as completed Hengke Casting projects or evidence of a rated capacity.
