Frequently Asked Questions


What comes in one of your raised floor kits?

We will figure all the floor system components needed based on the square footage you provide us.

The surface covering on the panels in the Kit have static dissipative high pressure laminate. This is the industry standard for equipment rooms. We offer the most popular color choice for a raised floor system, which is Grey Starlite. The white background is complimented by swirls of light gray. This pattern effectively hides surface dust extremely well and it requires little maintenance.

The Kit includes bolted stringer understructure. This provides the most lateral stability. It's very easy to self-install.


What kind of floors do you have?

All Steel panels are designed for ease of installation and frequent removal. Design load is 1250 pounds on any one square inch. Weight is 23 pounds. Used most frequently for server rooms where rows of racks are installed and foot traffic is present. The panels nest inside the grid formed by the stringers. All Steel panels are provided with high pressure laminate with integral trim.

ConCore panels are designed for repetitive rolling loads. Design load is 1250 pounds on one square inch. They are the heaviest panels at 35.5 pounds each and are hardest to remove from the grid. Used most frequently in areas where heavy carts, pallets and other loads are rolled over the same path frequently. The panels nest inside the grid formed by the stringers. ConCore panels are provided with high pressure laminate with integral trim.

Woodcore panels are basic utilitarian panels. They are rated at 1000 pounds on one square inch. They have good rolling load capabilities and they weigh 26 pounds each. Woodcore panels sit on top of the stringers, and are not captured by the understructure, therefore they are more subject to shifting or misalignment than other systems. Woodcore panels are provided with high pressure laminate and mechanically fastened edge trim. 

Aluminum panels are used in very specialized applications where a non-ferrous environment is needed. Most often this is in an MRI Exam Room, or a clean room at a computer chip manufacturing facility. Concentrated load rating is 1250 pounds on one square inch. They are the lightest panels at 23 pounds. Aluminum panels are made to interlock with the supporting pedestals and are provided without stringers. Aluminum panels are provided with high pressure laminate and mechanically fastened edge trim.


What height do I need?

Access Floor Kits are measured by the Finished Floor Height, which is the distance from the concrete slab to the TOP of the new walking surface. The pedestals are adjustable by 2" overall, one inch up and one inch down, to allow for corrections of slope in the subfloor.

Standard heights for our kits are 6, 12, 18 & 24" finished floor height. Most server applications and smaller network facilities are 6". Computer rooms range from 6" to 24" Some factors that may determine the height of a floor are ceiling height, existing doors, existing electrical outlets, and air flow.



How much floor do I need? 

To determine the amount of floor that you need, multiply the width of a room by the length to get the overall square footage of the area. If it's a portion of the room, figure the dimensions of the actual access floor area.  

For rooms not in 2' increments round up to the nearest full panel measurement. For instance a room measuring 23'7" x 48'5" should be figured at 24' x 50". Allowances for the swing of doors into the space and other components such as ramps can be deducted from the total square footage ordered. Panels can be field cut to fit using common tools.



What is a perforated panel? 

A special type of panel must be used to allow underfloor air conditioning to flow through the floor up to the equipment. These panels are sometimes called a perf, an airflow panel, air tiles, perforated panels, air vents, and louvers.

The traditional panels are called Perforated Air Flow panels because of the many holes drilled through them. They are exactly the same size and finish as the solid panels and are rated at 1000 pounds per square inch. These panels are 25% open area.  

We also offer grates for airflow. Grates are used when the heat of the equipment requires a higher volume of air. Grates are the same size as a standard access floor panel, but they are not covered with high pressure laminate.  

It is critical that you order the correct air flow panel to match your kit. We offer both All Steel / ConCore perforated panels and grates and Woodcore perforated panels and grates. These are not interchangeable.

To order special panels to match the panels at your facility, please visit the Panel IDC Center for more information.

If you are unsure how many perforated panels to use and want to continue with the Quick Quote Process, a non technical way to calculate would be somewhere between 1 per ton of air conditioning or one per 100 square feet of flooring installed. Please consult the advice of a HVAC Engineer for the exact number of Air Flow Panels required.


What about sealing the floor?

The grommets in this section are the industry gold standard for preventing airflow loss in raised floor environments. They all contain advanced foam or brush options for sealing technologies that are engineer-designed, field-tested and proven to work. Integrating these tools into your system is a highly effective way to reduce costs and save money.


How do I protect cables running through the floor?

Grommets are sleeves, which are installed into raised floor panels. They protect cables and computer room personnel from being cut by the sharp edges created after cutting into a panel for wire access. They slip into place and are held by gravity. There are no screws or other fasteners required.

Components are made from flame retardant A.B.S. resin, a durable strong plastic material, and are resistant to chipping or breakage. They have a two-piece snap-in swivel lid that accommodates cables and which also allows for partial opening or full opening with the lid in place. The inside lid adjusts to accommodate different cable sizes.

Please remember that a hole saw is required to cut the opening in a floor panel when using circular grommets.


What options are there for trimming the floor? 

Cut access floor panels are extremely sharp when cut for wire penetrations.  We offer several options to trim the cuts and protect both the wiring and the personnel in the computer room.


After years of experience we have found that making notches in the side of the panels, as opposed to a hole in the panel is much more user friendly. When there are problems with the wiring, simply remove the entire panel. Work in a 2' x 2' space then bunch the wires together and slip the notch back around them. With a round grommet, you are forced to try to get your hand thru the hole and work from under the adjacent panel or disconnect all the equipment.




How do I pick up the floor?

Once the access floor is installed you will need a tool to remove the panels from the grid. We recommend one lifter and one hanger for every 500 sq. feet of flooring.


The Panel Lifter and Holder Kit includes one 4" Double Suction Cup Lifter along with one Basic Panel Lifter Holder. This is the most popular option and keeps the lifter in a designated location for easy retrieval.


Our heavy-duty double suction cup lifter has two black 5" rubber cups mounted on a solid aluminum die-cast handle. This lifter is designed for use with concrete filled panels.




How do I clean the floor?


RISE Access Floor Cleaner has been formulated exclusively for use on access floors with a hard surface covering (high pressure laminate). Approximately 8 oz. will economically clean 1000 square feet of access floor.  RISE has been tested by high pressure laminate and access floor manufacturers.




How do I terminate the floor?


Access floor is designed to fill a room from wall to wall, however; if a door swings into a room you will need to allow a clear space to allow for the door to open without hitting the access floor or if only part of the room is covered with access floor you will need a closure kit to finish the edge of the access floor and keep debris from getting underneath. 


Closure kits are ordered by the height of your access floor and come in 4" increments. They are used to close off the open edge of the floor anytime it is not touching against a wall. For instance: if you have a door leading into your space, you need to allow for the door to swing into the room. You will need to provide a 4"x4" clear area without access floor. For a single door, which swings into the room, you will need 3 closure kits, one for straight ahead and one for the right and left sides.  Closure kits are also used along the side of a ramp or set of steps if it’s not against a wall.




Do you offer ramps?

Ramps are required by the Americans with Disabilities Act (ADA) to allow handicapped access onto the raised floor. There are very strict requirements for a ramp to comply with the ADA. The ramp slope (pitch) should be not greater than 1:12. This means for every inch your floor is raised your ramp must be at least 1 foot long. A 6” high floor requires a 6 foot long ramp, and a 12” high floor requires a 12 foot long ramp, etc. Additionally, the ramp must be at least 4 feet wide. Order ramp kits by the square foot, in 2 foot increments.


To determine the size of your ramp, multiply width times length. Remember that you should base the length on the height of your raised floor. Ramp Kits (purchased by the square foot) include everything needed to install a complete ramp. Our ramp kit includes: bare concrete filled panels, pedestal bases, ramp swivel pedestal heads, stringers, fasteners, aluminum ADA ramp shoe, galvanized steel bottom angle, ramp threshold, non-skid black ramp surface and adhesive. You may need to purchase a closure kit for sides of the ramp which do not touch a wall.


We offer a detailed explanation of the ADA (Americans with Disabilities Act) Codes relative to raised floor environments. Frequently Asked Questions about small equipment rooms. 



Do you have steps for raised flooring?

For a raised floor over 6 inches high, a step assembly with an intermediate tread is required. Steps are constructed by stacking raised floor segments on top of each other. The portion of a step assembly you stand on is referred to as the tread. The portion directly ahead of the toe of your shoe is called the riser. 

The Step Kit includes panels, pedestal bases, pedestal heads, stucco-embossed sheet aluminum fascia to make the riser, galvanized steel bottom angle, aluminum stair nosing (also called top angle) and fascia trim screws. A step kit for a 12” high floor has one tread and two risers. The step kit for an 18” high floor has two treads and three risers, and the step kit for an 24” high floor has three treads and four risers. Each kit includes sufficient material for a step 4 ft wide. If your door opening is wider you may need to order multiple kits.


Are safety rails needed? 

Handrail is defined as anything your hand touches going from one grade to the next. Not to be confused with guardrails, which prevent people from stepping off or falling off from one grade to the next. Handrails are typically wall mounted and are single rails.


Guardrails are defined as a means to protect equipment and personnel from slipping or stepping off of one grade to the next. Guardrails are typically floor mounted and are double horizontal rails with vertical posts. Guardrail should be placed anywhere in the room where the raised floor is over 6" in height.


Combo rails are a combination of a handrail and a guardrail. Combo rails are used along side ramps and steps, to provide a handhold when navigating the ramp.  


Rails are shipped in parts and are assembled at the jobsite. They are clear brushed anodized aluminum and meet ADA requirements. Order by the linear foot. 



What about shipping?

All of our prices are quoted FOB Origin. This means that freight IS NOT INCLUDED in our material prices. Freight charges are based on total weight and your destination zip code. We have negotiated exceptional rates with several freight carriers, but you are also free to use your own carrier.

Depending upon your individual job site requirements, the following services might be required if you do not have a loading dock at your facility:

Lift Gate: If your location does not have a loading dock or a forklift you will require lift gate service by the freight company to deposit the material on the sidewalk. This service does not include the freight company moving the material into your facility. It only includes lowering the material from the bed of the truck to the ground.
