Yellow Rain Coat 5T Top Factory
Yellow Rain Coat 5T Top Factory
Industrial-grade yellow rain coat rated for 5-tonne top load applications is engineered for use in heavy-duty material handling, mining, and port operations where exposure to precipitation and mechanical stress demands durable, high-visibility protective gear. This specification defines the minimum performance criteria for rainwear used by personnel working beneath or alongside elevated load paths in environments requiring compliance with occupational safety standards.
Material Construction and Performance Characteristics
The outer shell utilizes a 500 denier polyester base fabric with a polyurethane (PU) coating applied via calendar lamination to achieve a hydrostatic head rating of 8,000 mm, ensuring resistance to wind-driven rain under prolonged exposure. Seams are thermally welded using 20mm wide tape with a peel strength exceeding 15 N/mm, eliminating needle holes that compromise waterproof integrity. The coating adds 0.18 mm thickness per layer while maintaining flexibility down to -20°C, verified through ASTM D2136 low-temperature bend testing.
Reinforcement zones at shoulders, elbows, and seat incorporate a second layer of 1000 denier nylon oxford with TPU film lamination, increasing tear resistance to 45 N (ASTM D2261) in high-abrasion areas. The total fabric weight averages 320 g/m², balancing durability with wearer mobility. Colorfastness to UV exposure meets AATCC 16.3 Grade 4 after 100 hours of xenon arc testing, preventing premature fading of the high-visibility yellow hue critical for low-light condition detection.
Design Features for Industrial Use
The coat features a storm flap over the front zipper with magnetic closures at 50mm intervals to prevent water ingress during horizontal rain exposure, supplemented by an internal storm cuff with adjustable hook-and-loop seals at wrists. A two-way YKK AquaGuard® zipper (coil size 5) with drainable pull tab allows ventilation control while maintaining a water penetration resistance of 16,000 mm under static pressure (ISO 811).
Ventilation is managed through two underarm eyelets with hydrophobic membranes (air permeability: 8,000 mm/s, water resistance: >10,000 mm) and a vented yoke with mesh lining (100% polyester, 120 g/m²) to reduce internal condensation during high-exertion tasks. The hood is three-piece, adjustable via rear drawcord and side toggles, with a laminated peak extending 70mm beyond the forehead to shield the face without obstructing peripheral vision, tested per EN 17351:2020 for field of view retention.
Load Rating Context and Safety Relevance
The "5T" designation refers not to the garment’s load-bearing capacity but to its intended use in environments where overhead lifting equipment routinely handles 5-tonne loads, necessitating high-visibility apparel to mitigate struck-by risks. In such zones, personnel must be detectable at minimum 300 meters under low-light conditions per ISO 20471:2013 Class 2 requirements, which this coat exceeds through a minimum background material luminance factor of 0.75 and retroreflective tape performance of >300 cd/lx/m² at 5m.
Reflective trim consists of 50mm wide silver glass-bead tape applied to arms, legs, and torso in a biomotion configuration (horizontal bands at 50mm above elbow and knee, vertical strips on sides) to enhance motion detection. Tape adhesion is verified after 30 industrial wash cycles (ISO 105 C06) with no delamination or reflectivity loss below 80% of initial value. The garment does not provide fall protection or impact resistance; it is strictly a visibility and weather barrier system.
Quality Control and Manufacturing Consistency
Each batch undergoes hydrostatic head testing on three random specimens per 1,000 units produced, with acceptance criteria requiring all samples to exceed 7,500 mm. Seam strength is validated via grab test on five seam cross-sections per lot, with minimum elongation at break of 20% and load tolerance of 18 N/mm. Dimensional stability is assessed after five wash cycles at 60°C, limiting shrinkage to <3% in warp and weft directions to maintain fit and coverage integrity.
Color consistency is monitored using a spectrophotometer (CIELAB space) with ΔE < 3.0 against master batch standard for yellow (Pantone 803 C equivalent). Final inspection includes 100% visual check for coating defects, seam completeness, and fastener function, with AQL 1.0 for critical flaws (holes, open seams, missing tape) and AQL 2.5 for major defects (stitch skip, misalignment). All test records are retained for 36 months.
Applications in Heavy Industry
This rain coat is specified for use in open-pit mining operations where haul truck operators and ground personnel work beneath swinging dragline buckets or conveyor transfer points handling 5-tonne material loads. In port terminals, it is worn by stevedores and crane signalpersons during container stacking operations in tropical climates with sudden downpours, where visibility must be maintained despite wet surfaces reducing contrast.
Additional applications include railway maintenance yards during track realignment involving 5-tonne ballast regulators, steel mill ladle handling zones where splash protection from rain and incidental water contact is needed, and hydroelectric dam construction sites where personnel navigate spillway access routes during monsoon seasons. The garment is not intended for confined space entry, chemical exposure, or thermal protection scenarios.

Customization and Procurement Considerations
Standard sizes range from S to 3XL with chest measurements from 104cm to 156cm in 6cm increments, based on ISO 13688 body dimensions. Sleeve length and back length are proportionally graded; custom height adjustments are available upon request for non-standard anthropometry, requiring submission of chest, sleeve, and trunk measurements. Hood depth and peak angle can be modified to accommodate hard hat integration or specific visibility angle requirements.
Reflective tape width (30mm, 50mm, 75mm) and pattern (straight, chevron, biomotion) are adjustable to align with site-specific safety protocols. Alternative high-visibility background colors (orange, red) are available using the same PU-coated polyester base, though yellow remains optimal for low-light detection against natural backgrounds. Packaging options include individual polybags with desiccant or bulk packing in woven polypropylene liners inside cartons, with labeling compliant to ISO 17491-1 for chemical protective clothing (adapted for weather gear).
Minimum order quantity is 50 units for standard configurations; lead time averages 25 working days after sample approval and receipt of 30% deposit. Samples are available upon request, with shipping costs borne by the requester and credited toward the first order. Quotations require specification of size breakdown, tape configuration, color, packaging preference, and delivery terms (EXW, FOB, CIF).
