Extra-Large Truss and Pipe Ground Support

36 x 36 Inch Heavy-Duty Steel Truss Base Plate.
2 Inch Raised Frame for 12-Inch and 20.5-Inch End-Plate Truss Systems and 1.5 Inch Schedule 40 Pipe.

The EVT12S-BP36SR2 is a 36 x 36 inch extra-large steel truss base plate built from Q235 steel. Its 9 mm top plate sits on a 2 inch raised frame and includes a welded 1.5 inch Schedule 40 pipe flange and integrated carrying handles. It mounts to 12-inch and 20.5-inch end-plate truss systems and can also be used with 290 mm truss, and connecting hardware is included. At 171 lb, the base plate contributes substantial mass to a build, but it does not by itself establish adequate ballast, wind resistance, stability, or approval for a specific tower height or load.

Welded Pipe Flange
A welded 1.5 in Schedule 40 pipe flange provides a pipe-upright position.
Connecting Hardware Included
The source identifies connecting hardware as included. Confirm the delivered hardware list before installation.
One Interface at a Time
Use the intended truss or pipe interface according to the approved layout. Do not improvise a mixed connection arrangement.

When to Select It

Choose It When the Design Requires An Extra-Large Steel Ground Plate.

Select EVT12S-BP36SR2 when the approved design calls for a 36 x 36 in steel base plate for tall towers or heavy-duty rigging support. Product selection must be based on the complete connection and stability design, not on the plate’s weight, footprint, or raised frame alone.

Tall Truss Towers
For approved vertical truss assemblies using a compatible bolt pattern and complete stability design.
Pipe Uprights
For 1.5 in Schedule 40 pipe uprights when the flange position matches the approved layout.
Booths, Lighting Towers, and Event Structures
For planned ground-level support in trade show booths, lighting towers, and event structures.
Heavy-Duty Rigging Support
For applications that call for a large-footprint steel floor plate, subject to the complete project design.

Compatibility

Specified for EVT12S, EVT20S, EVT290S, and 1.5 Inch Schedule 40 Pipe Interfaces.

The product source identifies compatibility with EVT12S and other standard 12 in end-plate truss systems, EVT20S and other standard 20.5 in truss systems, 290 mm/F34 square truss systems, and a 1.5 in Schedule 40 pipe flange. These are interface categories, not automatic approval of every component combination. Verify bolt alignment, hardware, flange fit, upright orientation, load path, and project-specific engineering data before installation.

EVT12S and 12 Inch End-Plate Truss
Confirm the specific end-plate bolt pattern, bolt size, hardware, and required connection method before connection.
EVT20S and 20.5 Inch End-Plate Truss
Confirm the specific 20.5 in end-plate interface, required hardware, and the complete support arrangement before connection.
290 mm / F34 Square Truss
The plate can also be used with 290 mm truss. Half-couplers for 290 mm truss are sold separately. Verify the intended 290 mm mounting interface, hardware, and engineering data before connection.
1.5 Inch Schedule 40 Pipe
Verify pipe outer diameter, insertion, upright condition, retention, and the complete load case for the flange interface.

Installation Checks

Start with the Ground Surface. Then Verify the Connection and Complete Stability Plan.

A base plate is one element of a vertical structure. Installation requires a level and appropriate bearing surface, a verified mounting interface, correct hardware, plumb upright alignment, controlled loads, and any additional ballast or anchoring required by the complete design. These checks do not replace project-specific engineering review.

01 — Plan the Lift
The base plate weighs 171 lb / 77.56 kg. Use a planned team lift or appropriate mechanical handling method for the site conditions.
02 — Verify the Surface
Confirm the floor or support surface is level, stable, and appropriate for the complete base plate and structure load.
03 — Inspect the Base
Inspect the plate, raised frame, welds, pipe flange, handles, finish, and connection hardware for damage, deformation, cracks, or defects.
04 — Verify the Interface
Confirm bolt size, flange fit, retention method, and all fasteners for the specific truss or pipe component being installed.
05 — Check Plumb and Load Distribution
Set the vertical member plumb and confirm applied loads are distributed as required by the approved design.
06 — Add Required Stability Measures
Install specified ballast, anchors, guying, bracing, barriers, or other measures required by the complete structural and site plan.

Stability and Safety

171 Pounds of Steel Is a Product Fact. It Is Not a Universal Stability Calculation.

The base plate’s documented mass is 171 lb / 77.56 kg. Whether that mass is sufficient depends on the height and weight of the upright structure, center of gravity, applied and eccentric loads, wind exposure, floor condition, footprint, public access, impact risk, anchoring, ballast, bracing, and local requirements. Do not treat the base plate as self-ballasting for every tower, pipe upright, outdoor installation, or moving load condition.

A qualified professional must determine whether the base plate, ballast, anchoring, bracing, and support arrangement are adequate for the specific structure and site.
Additional ballast or other stabilization may be required for tall vertical builds, lateral loads, outdoor exposure, wind, uneven surfaces, public areas, or other site conditions.
Keep the vertical truss or pipe plumb and maintain the load distribution required by the approved design.
Do not use a damaged, bent, cracked, corroded, or otherwise compromised plate, raised frame, weld, flange, truss connection, pipe, or fastener.
Fully engage and secure all bolts, couplers, pins, cotter pins, or other required retaining hardware for the actual interface.
Use barriers, covers, markings, or other risk controls where the ground plate presents a trip, impact, or public-access hazard.

Extra-Large Steel Base Plate Questions

EVT12S-BP36SR2 Frequently Asked Questions.

What makes the EVT12S-BP36SR2 different from a flat steel base plate?

It uses a 9 mm steel top plate supported on a 2 in raised frame, with a 36 x 36 in footprint and a welded 1.5 in Schedule 40 pipe flange.

What truss systems can mount to the EVT12S-BP36SR2?

The product source identifies EVT12S and other standard 12 in end-plate truss systems, EVT20S and other standard 20.5 in truss systems, and 290 mm/F34 square truss systems. Verify the actual bolt pattern, connection hardware, and complete structural design before installation.

Does the 171 lb base plate eliminate the need for ballast?

No. The 171 lb product mass is a documented product fact, not a universal stability rating. Additional ballast, anchoring, bracing, or other stabilization may be required based on the complete structure, load, height, wind, surface, and site conditions.

Can the base plate be used outdoors?

Outdoor use requires project-specific evaluation of wind, anchoring, ballast, terrain, weather exposure, structure height, applied loads, and local requirements. The supplied product information does not establish a universal outdoor configuration.
