Frequently Asked Questions

Our products meet — and sometimes exceed — federal and state transportation agency standards for highway safety. Our products undergo challenging tests for safety and hydraulic efficiency to make sure we're ahead of the standards. This is one reason many engineers and designers specify J&J products by name.

Yes. We have end sections that connect to steel, concrete, HDPE, aluminum and aluminized Type 2 culvert pipe. J&J offers the widest selection of end sections in a variety of sizes and slopes in North America, including the metrics for the Ministry of Transportation in Canada.

Standard End Sections may be ordered in galvanized steel, aluminized steel (galvanized steel with an aluminum alloy coating) and aluminum. Safety Slope End Sections are available in galvanized and aluminized steel.

Both our standard flared end section and safety slope end section are available in a variety of sizes and slopes. The safety slope end section can be ordered with either traversable parallel or cross-drain bars. J&J was the first in the nation to develop the safety slope end section.

The lifespan depends upon the materials (galvanized and aluminized steel or aluminum) and can vary from region to region. Factors such as the environment and soil affect longevity. Easy attachment allows the end section to be reused should the pipe need to be moved, replaced or elongated, greatly increasing its lifespan.

J&J products are cut with exacting precision by our custom-designed Trumpf machine that ensures 100% computerized consistency within a product line. The Trumpf ensures a smooth, uniform fit time and time again, eliminating even minute variations.

A Type 1 strap with bolt and nut, or a Type 2 rod connector with nuts and side lugs are provided with all end sections. Installation requires only standard wrenches. For concrete and HDPE pipe, a smooth tapered sleeve is wedged snugly inside the pipe.

These end sections can be ordered with parallel or cross-drain bars in a variety of sizes and slopes. Bars are made from 3-inch pipe. Parallel bars are typically used under access ramps and driveways. Cross-drain structures are used primarily under major roadways and highways.

J&J offers the widest selection of end section slopes in the world. Standard end section slopes are 1.5:1 to 2.5:1 for both round and arched. Safety slope end sections are available in 4:1, 6:1 and 10:1 slopes.

The parallel bars are delivered unattached and can be easily assembled with standard wrenches. The cross-drain end section arrives as a welded grid. Bolt holes are prepunched in the end section walls for easy attachment. All pieces are shipped together.
