Stringers can be used to reinforce the static properties of the raised floor. There is a clip type, a bolted type, and clamp type stringers to choose from.
RO, RL (light) and RM (medium) stringers are made of cold-bent, galvanized steel sheet. The cross-sectional form of the RO-type is similar to that of a curved spring clamp. This allows the stringer to be installed by pressing vertically from the top. With the RL- and RM-types, the crosssectional form of which is U-shaped, there are springs located on the sides to prevent metallic rattling. Slots in the top side of the stringers are ideal for bolting with drilling screws.
