PERMANENT AND TEMPORARY

MDS® TL5 BARRIERS can be installed on structures as permanent  or temporary barrier when mounted back to back or used as bridge rail especially during construction and time sensitive rehabilitation projects that require relocating MDS® TL5 Barriers during phase oriented construction saving considerable amounts of time, materials & money.

NOISE & VISUAL PROTECTION

MDS® BARRIERS are pre-designed to integrate noise-protection sound barriers and site walls within a single barrier system providing considerable savings in terms of occupied space, supporting substructures and overall cost. The special backward positioning of the noise-protection barrier requires less lateral space on the bridge deck.

INSTALLING MDS TL5 BARRIERS

MDS® BARRIERS installation process is a straight forward

4 step process

1. Anchor plate into road surface / bridge deck *5"

2. Place and attach barriers

3. Tighten bolts

4. Mount upper tube rail

STEP 1

Install Anchor Plate

STEP 2

Place & Attach

STEP 3

Tighten Bolts

STEP 4

Mount Top Rail

PROVEN MDS® TL5 PERFORMANCE

MDS® BARRIERS have been tested to meet the highest performance standards in the world, passing both the American Standard NCHRP-350 Report 350 and MASH Test Level 5 including European Standard EN1317 Test Level H4b.

TRANSITIONS

MDS® BARRIERS transition into all guardrails, concrete barriers and end treatments for seamless integration.

SAFE & SECURE

With the ever increasing bridge rehabilitation projects emerging, the need for a light weight, high performance, easy to install TL4 and TL5 barrier for work zone safety has been a challenge. MDS® BARRIERS have been developed to provide the highest level of protection allowing job sites to start and end faster. The design simplicity of SRS anchoring system has no exposed plates or bolts that extend out from the barrier eliminating snagging especially in snow removing environments.

VLB BRIDGE EXPANSION JOINTS

Variable Length Barriers provide positive linear protection over bridge expansion joints expanding more than 27 inches maintaining TL5 protection.

SOUND PANELS STEEL

Metal sound barriers are made of galvanized steel, stainless steel or aluminum by cold forming process. Sound barrier panels provide a perfect noise protection and are resistant to atmospheric corrosion in industrial and seaside environments.

 

SOUND PANELS GLASS

Transparent sound barriers are made up of laminated glass panels fitted in aluminum frames.

Each frame is connected to the barrier posts by bolts and safety cables only in the case of extreme bolt failure.

Glass panels maintain excellent transparency in all weather conditions and guarantee maximum noise protection in any location where noise pollution is an issue, such as highways and residential areas.

 

SAFETY SOUND PANELS

Protect bridge decks from public abuse and projectiles. Enclose construction sights discouraging visibility and access. Provide full scale wide area protection for high threat areas for absolute containment.

 

VARIABLE LENGTH BARRIER

MDS® Variable Length Barriers (VLB) eliminate the gaps on bridge deck expansion joints by expanding and contracting more than 27 inches. Use for continuous protection over bridge expansion joints or were excessive barrier expansion & contraction is anticipated. MDS® VLB barriers can also be used on new bridge expansion joints avoiding the need to build custom design manufacturing.

 

Service expansion joints without having to remove the barrier

 

REFLECTIVE SAFETY

Genuine US Reflector safety barrier reflective devices define and illuminate roadways around the world. No other reflector comes close to the quality and clarity of high power prismatic technology. Use on all MDS® BARRIER products and standard concrete barriers and poles for absolute crystal clear safety in all colors.

 

 

BARRIER GLOW

Not all reflective devices are made equal. Discover BarrierGlow, a photoluminescent stripe of light creating linial visibility. BarrierGlow is a complimentary addition to traditional reflective devices. Improve motorist visibility through workzones. Developed exclusively for MDS® BARRIERS with StepGlow® technologies, BarrierGlow® adhesive strips changes the way we all see the road ahead.
