The DF110C screed plate is a wear component for the Demag DF110C asphalt paver screed system. Manufactured by JST, this bottom plate contacts the asphalt mat directly during paving and determines the surface finish, flatness, and initial compaction of the paved layer. It is available in Hardox 450 and NM400 abrasion-resistant steel options to suit different project specifications and aggregate types. The plate is produced to Demag DF110C screed dimensions for direct bolt-on replacement and is covered by a 1-year warranty.
The DF110C screed plate is offered in two abrasion-resistant steel grades. Hardox 450 provides a nominal hardness of 450 HBW, suitable for standard asphalt mixes and general highway paving. NM400 offers a nominal hardness of 400 HBW and is selected for projects requiring a balance between wear resistance and plate formability. Both materials resist the abrasive action of aggregate in hot asphalt mix.
The screed plate is manufactured to Demag DF110C screed dimensions and mounting hole patterns, allowing direct bolt-on replacement without modification to the screed frame. The plate matches the original equipment profile for screed width and thickness, ensuring consistent paving performance after installation.
The bottom surface of the screed plate is precision-machined to maintain uniform contact with the asphalt mat across the full paving width. This contributes to consistent surface flatness and helps achieve the target pavement smoothness required on highway and urban road projects.
The DF110C screed plate is used on Demag DF110C asphalt pavers in the following applications: highway and expressway asphalt surface courses, urban road and street paving projects, airport runway and taxiway asphalt layers, parking lot and industrial yard paving, and bridge deck asphalt overlay projects.
In each application, the screed plate performs the final leveling and initial compaction of the asphalt mat after the tamper bar has pre-compacted the material. Paving thickness typically ranges from 3 cm to 15 cm for standard layers, with the screed plate maintaining consistent thickness through hydraulic or mechanical adjustment. The screed also controls cross slope to meet design elevation and drainage requirements.
Hardox 450 is a quenched and tempered abrasion-resistant steel with a nominal hardness of 450 HBW. It is recommended for projects using coarse aggregate asphalt mixes or for high-volume paving contractors seeking extended plate service life. The higher hardness level provides improved resistance to aggregate scratching and surface wear.
NM400 is a Chinese-standard abrasion-resistant steel with a nominal hardness of 400 HBW. It is suitable for standard asphalt mixes and routine paving applications where a cost-effective wear plate is required. NM400 offers good weldability and can be repaired by hardfacing if surface wear occurs during a project.

Before installing a new screed plate, inspect the screed frame for flatness and verify that all mounting surfaces are clean and free of old asphalt residue. Install the plate using the original mounting bolts and torque to the manufacturer's specification. After installation, check screed flatness with a straightedge across the full width.
For maintenance, inspect the screed plate surface daily during active paving for signs of uneven wear, scoring, or deformation. Clean the plate surface at the end of each paving day to remove accumulated asphalt. Replace the screed plate when wear reduces the original thickness by more than 20 percent, or when surface scoring affects pavement finish quality. For volume pricing and delivery schedules, contact JST with your material preference and project timeline.
The DF110C screed plate is available in two abrasion-resistant steel grades: Hardox 450 (450 HBW nominal hardness) and NM400 (400 HBW nominal hardness). Both options are suitable for hot asphalt paving applications.
Replace the screed plate when plate thickness has been reduced by more than 20 percent from the original dimension, when surface scoring affects pavement finish, or when the plate shows visible deformation or cracking.
Yes. Both material options are manufactured to the same DF110C screed dimensions and mounting patterns. The choice between Hardox 450 and NM400 depends on project requirements, asphalt mix type, and expected service life.
The DF110C screed plate is covered by a 1-year warranty from the date of delivery, covering manufacturing defects in material and workmanship under normal asphalt paving operating conditions.
