Regular Visual Inspection and Damage Detection.

The first step towards a robust maintenance plan is damage assessment to complete your metal guardrails. Monthly assessments are recommended to observe and assess visual symptoms of metal guardrail damage, such as beams deteriorating, metal guardrail bolts becoming loose, and guardrail posts becoming misaligned. These observations are particularly crucial on guardrail areas that are prone to accidents and have poor visibility, such as road bend, and uphill and downhill driving sections. Metalguardrails suggests a professional line of service to cover areas of intricate design for a complete maintenance service. The supplemental service is to observe and assess the metal guardrails with the service of a professional. Evaluating the service of a professional will cover the metal guardrails for areas that are inaccessible with the use of reserve and invest in parts of the metal guardrail that have parts deteriorate. Therefore professionals will reserve the metal guardrails from deteriorating parts, and from critical damage.

Surface Maintenance and Prevention of Corrosion

The greatest danger of corrugated steel beam guardrail is corrosion. Metalguardrails' products are hot-dip galvanized and meet ASTM A123 standards, but corrosion can still occur. Regular maintenance is still required. In coastal and snowy areas, guardrails should be maintained quarterly. Minor scratches and other damage to galvanized layers can cause rust to develop. To prevent rust from spreading, use Metalguardrails' anti-rust paint. In areas with high humidity, additional anti-corrosion coating can be applied. These methods can extend the service life of the guardrails to over 20 years.

Reinforcement of structure and tightening of bolts

The structural integrity of a section of corrugated steel beam guardrail can be adversely affected by loose bolts and connections. Check the beam-post connections and foundation bolts every 6 months, and apply a torque of 45-55 N·m to the bolts with a torque wrench. Metalguardrails’ original spare parts should be used to replace any bolts that are worn or damaged. To guardrail sections that have sustained impact damage, use support brackets to reinforce the structure or replace bent parts. The parts of Metalguardrails’ modular design are easily replaced, allowing maintenance to be done quickly.

Vegetation and Debris Clearance

Regular maintenance of guardrails includes clearing the area of weeds and any sort of vegetation build up. Weeds and shrubs should be cleared out every couple of weeks, to make sure that the guardrail does not get damaged and retains no moisture. Remove debris like rocks, trash, and sticks that could clog the guardrail's drainage systems and that could damage the guardrail. Also, make sure that the drainage systems at the bottom of the guardrail are not blocked to keep the soil from washing out and the posts getting damaged. All of these actions are needed to make sure that the guardrails are operational and that the function they serve will not be negatively affected.

 Seasonal Maintenance Adapted to Environmental Conditions

To address maintenance needs, the maintenance schedule should be adapted based on the season. If winter brings snow, and road salt needs to be applied, do so, and remove any winter ice build up so the guardrails do not become compromised from the weight of the ice and from the chloride of the road chemicals. During the hot summer months, guardrails should be inspected to fix issues that stem from the heat, like loose components from thermal expansion. If rain is frequent, maintenance checks should be completed more often, and drainage systems should be inspected. Seasonal maintenance guides are provided to customers by Metalguardrails to adapt to the season and maintain the corrugated steel beam guardrails.
