HEL-COR Deck Drain is a perforated drain system used in the construction of railroad bridges. This efficient system utilizes half-round perforated corrugated steel covers with a steel plate bottom to drain the ballast at the bottom of the railroad bridge. Steel is used to manufacture Deck Drain because of its superior strength and long-term durability compared to plastic drain products. Contech® Deck Drain is a proven solution and has been used in railroad bridge construction for decades.
Bridges are often designed from zero to very minimal gradients, and designers must also mitigate the water from ponding and running off the ends of the bridge. Railroad bridges are constructed with ballast instead of pavement, and Contech Deck Drain is used to collect and transport water off of the bridge.
HEL-COR® Deck Drain covers are manufactured with 8” half-round corrugated metal spans in 12-gage, 14-gage, or 16-gage galvanized steel that are 24” long after overlap. Standard pan lengths are 10’ long. Deck Drain can also be asphalt coated. The end corrugations are overlapped in the field for the connection. Adjustments for length can be made by overlapping additional corrugations to make up site specific custom run lengths.

HEL-COR® Deck Drain is a perforated corrugated steel drainage system designed specifically for railroad bridge applications. It uses half-round perforated corrugated steel covers with a steel bottom pan to collect and transport water away from railroad bridge ballast systems.
HEL-COR® Deck Drain is primarily used for:
It is engineered to efficiently remove water from railroad ballast systems where bridges are designed with a minimal slope.
Railroad bridges are often constructed with little to no gradient, which can allow water to pond within the ballast section. HEL-COR® Deck Drain helps remove trapped water, reduce ballast saturation and helps maintain track stability and bridge performance.
HEL-COR® Deck Drain is manufactured from galvanized corrugated steel because of its superior strength and long-term durability compared to plastic drainage products. Asphalt-coated options are also available for additional protection.
Standard HEL-COR® Deck Drain includes:
Yes. While the standard configuration uses an 8” half-round profile, custom sizes and configurations are available depending on project requirements.
The corrugated cover sections overlap at the ends in the field to create the connection. Additional overlap adjustments can be made to accommodate non-standard run lengths and site-specific conditions.
Yes. Installers can modify run lengths by overlapping additional corrugations during installation, allowing flexibility for custom bridge layouts and drainage runs.
HEL-COR® Deck Drain is available in:
These coatings help improve durability and extend service life in harsh railway environments.
Steel provides:
These characteristics make steel deck drains better suited for railroad bridge applications than plastic alternatives.
HEL-COR® Deck Drain has been used in railroad bridge construction for decades and is considered a proven drainage solution within the rail industry.
HEL-COR® Deck Drain utilizes HEL-COR 2-2/3" x 1/2" corrugation profiles, providing structural rigidity and drainage performance for railroad bridge environments.
By efficiently removing water from ballast trough systems, HEL-COR® Deck Drain helps:
Yes. The overlapping corrugated cover design simplifies field assembly and allows contractors to make length adjustments without complex fabrication. Standardized sections also help with installation on railroad bridge projects.
Key advantages include:
These features make HEL-COR® Deck Drain a reliable solution for railroad bridge drainage systems.
