Practical Guide for Traffic Sign Maintenance in High‑Temperature & Rainy Seasons
In summer, alternating intense heat, scorching sunshine and heavy rain‑wind conditions often cause traffic sign defects such as reflective film peeling and fading, loose support bolts and metal‑component corrosion. These problems directly impair sign visibility and road‑traffic safety.
Founded in 2002, JKTRAFFICLIGHT has specialized in manufacturing traffic‑safety products for over two decades. Drawing on extensive production know‑how and field experience, we have compiled the following maintenance guidelines.
1. High‑Temperature Exposure: Prevent Aging & Looseness
Continuous UV radiation accelerates fading and peeling of conventional reflective films. Thermal expansion and contraction reduce the pre‑tightening force of bolts on metal supports.
Maintenance Tips During routine inspections, check the condition of reflective films. Seal minor edge‑lifting and partial damage with special‑purpose adhesive to stop moisture and dust from worsening defects. Replace or refurbish panels with severe aging, discoloration or degraded retroreflective performance to guarantee visibility. Re‑inspect connection bolts of columns and flange plates monthly. Reserve proper expansion gaps during installation.
JKTRAFFICLIGHT Product AdvantagesJKTRAFFICLIGHT Traffic Signs adopt high‑weather‑resistant reflective films with excellent anti‑UV performance and stable long‑term retroreflectivity. Matched hot‑dip galvanized supports feature high‑temperature resistance and corrosion resistance, minimizing potential looseness and corrosion at the source.
2. Rainy Humid Conditions: Prevent Water Accumulation & Corrosion
Long‑term rain exposure and water pooling at base sections are major triggers for corrosion on sign columns and fasteners. Moisture penetrating metal gaps triggers progressive oxidation. Surface rust can develop into deep‑seated corrosion, weakening structural strength, seizing bolts and damaging columns, which drastically shortens service life. Aged sealing gaskets may also lead to moisture ingress inside electronic signs.
Maintenance Tips Clear drainage holes at the bottom of signs before rainy seasons. Verify sealing performance of junction boxes for light‑equipped and electronic signs. Remove surface rust promptly and apply touch‑up paint to halt corrosion spread and protect metal substrates.
3. Severe Convective Weather: Wind‑Resistance Reinforcement
Summer thunderstorms, gales and typhoons exert heavy impact on sign structures. For high‑mast signs on open sections or viaducts, loose anchor bolts, offset flanges and frame deformation may occur; in worst‑case scenarios, tilting or collapse can take place.
Maintenance Tips Before and after rainstorms or gales, inspect critical load‑bearing components including anchor bolts, flange plates and main columns. Retighten loose fasteners. For large‑size signs in fully‑exposed locations, add diagonal bracing as required to improve overall wind‑resistance stability.
4. Special Maintenance for Electrical‑Type Traffic‑Safety Products
Electrical products including traffic signals, radar speed feedback signs and traffic warning lights require targeted maintenance under high‑temperature and rainy conditions. Inspect sealing gaskets, junction boxes and conduit fittings for water tightness; drain trapped water and replace deteriorated sealing parts. Clean solar panels of speed signs and warning lights regularly to secure stable power supply. Check lightning‑protection earthing and wiring before thunderstorm seasons to avoid short‑circuits and equipment failure.
