Q. Can this be used in soil affected by salinity?
A .Yes. Please refer to the Instruction Manual for details.
Q. Can the standard type withstand a person’s weight? Can it act as a passage?
A . The standard type is not designed to be load-bearing. There is a walkway type designed to bear the weight of an average person. However, it is only meant to be used as a temporary path for maintenance purposes and not as a normal walkway.
Q.The surface is starting to rust. Is it not resistant to corrosion?
A . It is corrosion resistant but not corrosion proof. Scratched on the surface made during the installation a nd regular use may cause rust to appear prematurely. Additionally, over many years, the layers of zinc protective coating will degrade and rust may appear. Please refer to the Product Catalog or Instruction Manual for details.
Q. I want to switch from the standard type to the walkway type. Can I just change out the cover?
A . No. The supports will have to be upgraded to the heavier-duty types to support the additional weight.
Q.What kind of brackets should I use to mount it on the wall?
A . Please use the S Type RZM Bracket and RZB Riser. When doing the RD-150 type installation, please use the 300 S Type or other brackets (such as RZW) used for mounting to the wall. Please do not use a bracket that is longer than the S type because it will lose its center balance on the wall and problems resulting from the installation may arise. Please use an S Type or some other bracket meant for the wall.
Q. Is it possible to buy just a reinforcement plate?
A . Yes. Please contact Inaba Denko-America or your nearest dealer.
Q. Do I need a wall plate or wall sleeve?
A . Generally speaking, yes, it is necessary. A wall plate or wall sleeve is used to prevent and dispose of rainwater penetrating the building. You can do without a wall plate or wall sleeve by disposing of water in other ways such as creating a chamber box.
Q. If I install a standing Wall Sleeve or Wall Plate, will it completely stop the water?
A . If it is installed as per the Instruction Manual, the standing water can be prevented. However, there is no guarantee of that in all cases. The wall plate has been tested and confirmed that there were no signs of water penetration when installed properly.
Q. Can I use a free joint in place of a fixed joint?
A . If it sits level to the ground, yes. However, it is not recommended since the degree of strength after installation declines over time. For better fitting, refrain from continuous use of free joint and corner connections.
Q. What should I know when cutting a straight line duct?
A . Please use a high-speed cutter (nippers, snips, cutting wheel, etc.). If it is larger than the 450 type, we recommend using a cutting wheel. To prevent the cut surface from corroding, make sure after using a file to deburr the cut edge, apply an anti-rust treatment (a Zn-Al type or zinc-rich paint).
