Raised Floor Pedestal LH-2

Overview

Raised Floor Pedestal LH-2 consists of a base plate, tube, threaded rod, head plate, toothed lock washer, height adjustment hexagon nut and PP conductive plastic gasket. Raised Floor Pedestal LH-2 is compatible with wood core panel, calcium sulphate panel, aluminum panel (panel size : 600 mm × 600 mm).

The raised floor pedestal can provide ± 20 mm (± 0.78") vertical adjustment. LH-2 series pedestals installed with raised floor panels are able to reach finished floor heights (FFH) from 130 mm to 600 mm (5.11" to 23.6"). For lower pedestal please check Raised Floor Pedestal LH-1.

The whole raised floor understructure LH-2 includes pedestal LH-2 and stringer LH. The use of bolt-on stringers can highly increase loading capacity and lateral stability.

Range of Finished Floor Heights From 150 mm to 600 mm (5.9" to 23.6")
Range of Tube Heights From 70 mm to 500 mm (2.75" to 19.68")
Range of Height Adjustment ± 20 mm (± 0.78")
Pedestal Axial-Load Performance 29.5 kN, 3015 kgf, 6646.9 lbf
Stringer Concentrated-Load Performance 2.74 kN, 280 kgf, 617 lbf
Coating Raised Floor Pedestal LH-2 is plated in yellow zinc, and Raised Floor Stringer LH is coated with electrophoretic deposition. Other coatings are available upon request.

raised floor pedestals


Please note that the stringer and pedestal head plate’s tapped holes can be customized to fit your panel.

1. Panel sizes may differ from manufacturer to manufacturer, but we can adjust the stringer size to fit varied sizes and shapes of panel, please inform us your demanded stringer dimensions.

2. If you use Cornerlock raised floor panel, please specify the position and size of the head plate’s tapped holes for panel mounting, and we will manufacture the pedestal to suit your panel.

Features

1. The raised floor pedestal components are pre-assembled to reduce your installation time.

2. Upon customer’s request of earthing (grounding), an earth screw point on the base plate will be tapped and a M6 screw will be provided. Installation of earth bonding can be realized by passing and tightening a M6 screw through your wire connector.

3. Raised Floor Pedestal Axial Load Test :
Raised Floor Pedestal LH-2 is tested in accordance with the test procedures set forth in Ceilings & Interior Systems Construction Association CISCA A/F, Section 5 and European Standard En12825. The Raised Floor Pedestal LH-2 is capable of withstanding 54 kN, 5515 kgf, 12158.49 lbf axial load per pedestal.
(The test result is based on FFH 25cm pedestal, tube outside diameter: 23.5 mm)

4. Raised Floor Stringer Load Testing :
Raised Floor Stringer LH is tested in accordance with the test procedures set forth in Ceilings & Interior Systems Construction Association CISCA A/F, Section 4 and European Standard En12825. The Raised Floor Stringer LH is capable of withstanding 2.74 kN, 280 kgf, 617 lbf concentrated load per stringer.
(The test result is based on hollow square section stringer, thickness: 0.75 mm)

5. Panel installed with Raised Floor Pedestal LH-2 can reach finished floor heights from 150 mm to 600 mm (5.9" - 23.6"). Requirement for FFH below 150 mm (5.9") please check Raised Floor Pedestal LH-1. Higher access floor pedestals are available upon request.

6. Height adjustment range ± 20 mm (± 0.78"). Access floor pedestals with wider adjustment ranges are also available upon request.

7. The height of head plate can be adjusted by turning a 3/4" toothed lock washer and a 3/4" hexagon nut.

8. Bolt-on access floor stringer (hollow square section) can increase lateral stability and add additional load bearing.



Coatings

1. Generally the whole access floor pedestal is coated with yellow zinc to prevent rusting, and stringer is coated with E-coat (electrophoretic deposition, EPD). Other coatings are available upon request.

2. In industrial application where acid or alkali resistance is needed, the access floor pedestal will be coated with polyvinylidene difluoride (PVDF) to prevent corrosion from acid or alkali exposure.

3. If highly corrosion resistant coating (anti-rust coating) is required, we suggest you to have the raised floor understructure coated with hot dip zinc galvanization or DACROMET plating.

4. To prevent zinc whisker contamination, we suggest other surface finishing such as powder coating, hot dip zinc galvanizing or nickel plating.

5. Hot dip zinc galvanized threaded rod can be made available but not recommended, because it would be difficult and costly to remain the thread dimensions within the original specifications. We would suggest you to choose other alternatives, such as PVDF, DACROMET or powder coating.

6. If you need to check corrosion resistance of specific coating or specific coating thickness, the coated component or product will be tested in neutral salt spray test and the report will be provided for you.

7. Should you have any special requirements for the corrosion resistance of the pedestal, please inform us. We will do our best to meet your requirements.
