As a core auxiliary material for exterior wall insulation, interior wall leveling, building waterproofing, tile installation and other construction projects, the quality stability of fiberglass mesh directly determines subsequent construction effects, project durability, as well as customers’ engineering reputation and cost control. Many customers have frequently reported a common problem to Yuniu: fiberglass mesh that passed quality inspection upon purchase often becomes soft from moisture, moldy on the surface, yellowed at the edges, and loses tensile strength after a period of storage. In severe cases, it becomes unusable, causing direct material waste, construction delays, and increased labor and procurement costs—all unnecessary losses.
In fact, the core of fiberglass mesh storage management is humidity control + sterilization. With 24 years of expertise in the fiberglass industry, Yuniu is a professional enterprise integrating R&D, production, sales and service. Relying on three production bases, intelligent production lines and strict quality control, combined with years of practical experience, we have developed a fully implementable storage, sterilization and moisture‑proof solution to help customers maintain material quality and reduce losses.
The material properties of fiberglass mesh demand strict storage conditions. Made primarily of fiberglass yarn and thermosetting resin, fiberglass itself does not absorb water, but the resin layer softens and ages easily when exposed to moisture. Excess humidity penetrates packaging, weakens bonding between fibers, and causes loosening and deformation. Meanwhile, humid environments quickly breed mold, which ruins appearance, erodes the resin layer, and degrades key properties including alkali resistance, tensile strength and crack resistance.
In construction, this can lead to wall cracking, tile detachment, or even compromise the stability of the entire insulation and waterproofing system, creating safety hazards. Yuniu fiberglass mesh uses high‑alkali‑resistant coating and optimized mesh structure, offering excellent dimensional stability, aging resistance and corrosion resistance. With proper storage, its service life is greatly extended.
Storage environment control is fundamental yet often overlooked. Most moisture damage stems from poor environmental management. Yuniu recommends:
Store only in dry, ventilated, indoor warehouses away from direct sunlight and odors. Avoid low‑lying, damp, open‑air or flood‑prone areas to prevent rainwater backflow, groundwater dampness or dew erosion. Maintain waterproofing on roofs and walls and inspect regularly for leaks.
Keep temperature at 15°C–35°C and relative humidity strictly at 35%–65%. This range prevents resin aging and inhibits mold. Install 1–2 thermo‑hygrometers in each zone (entrance, corners, shelves), assign staff to record data daily, and act immediately if humidity exceeds limits.
For rainy seasons, plum rains or high‑humidity coastal areas, use industrial dehumidifiers (one 50L/day unit per 100㎡) and exhaust fans for air convection. Ventilate on sunny days from 10:00 to 15:00; avoid rainy, foggy or cloudy days to prevent external moisture intrusion.
Placing mesh directly on floors, against walls or over‑stacking causes moisture and damage. Follow these rules:
Elevate rolls at least 15 cm on wooden or plastic pallets and keep 30 cm away from walls. This blocks condensation and wall dampness and improves airflow.
Prefer vertical storage on dedicated racks to avoid deformation and edge damage. If horizontal stacking is necessary, limit height to 1.5 meters and place support boards every 3–4 layers to distribute pressure.
The factory package is the first moisture barrier. Keep it sealed and intact. Yuniu mesh uses thickened waterproof laminated woven bags, individually sealed with desiccants to block moisture, dust and contaminants—ready for direct storage.
Sterilization and inspection are critical to prevent mold and detect issues early:
Place silica gel desiccants or activated carbon in storage areas and corners, replacing every 1–2 months. Perform full sterilization monthly using non‑toxic, non‑corrosive, eco‑friendly agents, focusing on corners, pallet bases and shelf gaps. Avoid direct contact with mesh to protect resin and fibers. Increase frequency if mold appears.
Inspect fully every week for damaged packaging, mold, yellowing, softness or dampness. Isolate and air‑dry slightly damp rolls; discard severely damaged items. Monthly checks should cover humidity records, dehumidifier operation, roof and pipeline leaks, and drainage ditch cleaning.
Adapt to seasonal climate changes with these guidelines:
If warehouse temperature drops below 15°C, acclimate mesh at above 23°C for 24 hours before use to prevent brittleness and breakage. Ventilate briefly at midday on sunny days to avoid cold drafts and condensation.
High heat and humidity bring peak mold risk. Extend dehumidifier use, ventilate 2–3 times daily for 30+ minutes, and reduce stacking density for better airflow. Keep windows closed in rain; use canopies during loading/unloading. Dry or replace wet packaging immediately before storage.
Handle materials gently to avoid packaging damage. Inspect packaging for integrity and dryness before warehousing.
