Tensioners, end terminals, cross clamps and stainless cable must form a compatible assembly. State cable construction, diameter, grade, connection method and documented capacity in the order.
Concealed swaged assembly inside a stainless post
Confirm manufacturing tolerances, thread specification, alloy and any required certificates for the selected component before ordering.
A swaged terminal and tensioner arranged inside the post. Compatibility depends on cable, internal dimensions, adjustment access and the selected fitting's instructions.
A threaded tensioning mechanism selected for the cable, end restraint and available adjustment access. Confirm assembly and locking instructions before installation.
Select the seating and articulation range for the stair angle, cable path and post geometry. Confirm the permitted angles from the component drawing.
Cross clamps position cable intersections. Verify cable compatibility, slip resistance and the complete infill geometry; a cross clamp alone does not establish an anti-climb barrier.
Cable construction affects flexibility, stretch and end-fitting compatibility. State grade, diameter, construction and surface condition in the order.
Select anchors for concrete condition, loads, edge distances, spacing and the manufacturer's instructions. Verify tension and shear together where required.
The alloying element molybdenum can improve 316 stainless resistance to some chloride corrosion mechanisms compared with 304. The actual environment, temperature, finish, detailing and cleaning still determine suitability.
Where testing is required, state the method, conditions, acceptance criteria and traceability to the supplied batch. Salt-spray results alone are not a service-life prediction.
| Element / mechanical criterion | 316 stainless steel | 304 stainless steel | Effect on system performance |
|---|---|---|---|
| Molybdenum (Mo) | 2.00% - 2.50% | Confirm composition against the material certificate. | Select the alloy for chlorides, temperature and cleaning. |
| Nickel (Ni) | 10.0% - 14.0% | 8.0% - 10.5% | Alloy behaviour and magnetic response depend on composition and processing. |
| Chromium (Cr) | 16.5% - 18.5% | 18.0% - 20.0% | Contributes to the protective passive layer. |
| Yield strength | ≥ 290 MPa | ≥ 205 MPa | Assess thread and component capacity from material and connection data. |
| Wind design and safety factors | Factor 2.5x | Factor 1.2x | Assess roof and coastal exposure for the complete system. |
Enter geometry for an initial quantity estimate. The result is not a structural design or a verification of safe cable spacing.
Cable tension, span, temperature changes and post anchorage affect performance. Set re-tensioning requirements in the service plan for the installed system.
Fittings must suit the cable diameter and construction, connection geometry, adjustment range and corrosion exposure. Specify fitting and cable materials and anchorage details in the order. Appearance, branding or nominal diameter alone does not establish connection capacity.
