Product Overview

The PP walkway plate is a corrosion-resistant and slip-resistant walkway board designed for installation on electroplating production lines, acid washing tank edges, and chemical plant operation areas. Made from PP material through injection molding, the plate is highly resistant to deformation. The surface features anti-slip protrusions to enhance friction, while the open holes allow for rapid drainage of splashed acidic or alkaline liquids, keeping the working surface dry and ensuring operator safety.

Grounds in electroplating and chemical workshops are frequently exposed to acidic, alkaline, and corrosive chemicals. Steel grating is prone to rusting, while conventional flooring can delaminate and deteriorate when exposed to prolonged moisture. PP walkway plates are acid and alkali resistant, water-absorbent, and rust-free. They provide excellent slip resistance even on wet edges and are lightweight, making them easy to transport and install. Each plate can be individually replaced for maintenance, making them a common surface protection accessory in surface treatment workshops.

The PP walkway plates supplied by Xichen Environmental are standard injection-molded plates with edge splicing and fixing structures, allowing for continuous paving along production lines and walkways. They are supported by brackets or beams below, with splashed liquids draining into ground-level drainage channels. These plates can also be used for equipment maintenance platforms, top operating areas of towers, and walkway covers for corrosion-resistant trenches.

Working Principle

The anti-slip mechanism of the walkway plate comes from its anti-slip protrusions and grid texture. The protrusions create multi-point contact between the sole and the plate, disrupting water films on the foot and increasing friction resistance in wet conditions, thereby reducing the risk of slipping on liquid-covered surfaces. The open holes allow for timely drainage of splashed chemicals and rinsing water, preventing liquid accumulation and reducing slipperiness.

The corrosion-resistant principle stems from the chemical stability of PP material. Polypropylene does not react with common acids, alkalis, or salt solutions. When chemicals are splashed onto the plate, they either drain through the holes or remain on the surface, unlike steel which rusts and thins, or wood which absorbs water and decays. The elevated installation allows for ventilation beneath the plate, preventing prolonged liquid accumulation and further extending its service life.

Structural Composition

The walkway plate is integrally injection-molded from a panel, anti-slip protrusions, liquid drainage holes, reinforcing ribs, and splicing edges. The panel serves as the walking surface, featuring a dense array of anti-slip protrusions or patterns, with regularly distributed long-round or rectangular drainage holes. The back features transverse and longitudinal reinforcing ribs, ensuring load-bearing capacity and dimensional stability, especially in areas with numerous holes, preventing noticeable deflection under foot traffic.

The edges of each plate are designed with splicing edges and connection holes. When multiple plates are joined, the splicing edges overlap, and they are fixed to brackets using plastic fasteners or bolts, forming a continuous and smooth walkway. Edge plates and corner plates can be cut or paired with custom-shaped components. The plates are supported by corrosion-resistant brackets, with the height adjustable based on drainage and diversion needs. Slopes or steps are provided at the ends for easy access.

Typical Process Locations

Foot plates are installed along the sides of plating tanks, pickling tanks, and various wet process production lines. Workers perform tasks such as loading and inspection on the plates, while splashing chemicals from the tanks are drained through leak holes. The plates also surround reaction vessels, storage tanks, and tower operation areas, forming corrosion-resistant and slip-proof walkways. The plates are supported by frames and connected to the workshop's drainage and collection systems.

In workshop floor construction, foot plates are placed above corrosion-resistant flooring or drainage channels, serving as the direct contact surface. Installation begins with fixing corrosion-resistant brackets and crossbeams, followed by laying the plates in sequence and securing them with fasteners. Edge and corner treatments are applied to ensure flatness and stability. The plates are cut to fit around tanks, columns, and other equipment, eliminating large gaps and trip hazards. Before installation, the plates are cut to match tank and walkway widths, with crossbeams leveled and secured before sequential placement. Locking mechanisms or connectors are used to fasten plates together, with edge and corner treatments ensuring stability. Drainage holes must remain unobstructed, and concentrated loads or heavy impacts on the plate surface must be avoided. Regular cleaning of the plate surface and drainage channels is required to remove chemical deposits, along with inspections for corrosion, cracks, or loose fasteners. Damaged components should be replaced or reinforced promptly.

The foot pedal is designed based on personnel walking and conventional operational loads. The reinforced ribs on the back ensure that it does not deflect or crack under normal stepping by one or multiple people, meeting the needs for side-channel inspection and upper/lower hanging operations. Whether it allows for forklift passage depends on the pedal thickness, rib structure, perforation rate, and support spacing. The forklift load is significantly greater than pedestrian loads, requiring denser supports and the selection of heavy-duty, thickened foot pedals. When selecting, clearly provide load conditions such as forklift passage, wheel ground pressure, and frequency, configure the plate thickness and supports according to heavy-duty requirements, and avoid estimating based on standard pedestrian foot pedals. Standard pedestrian foot pedals should not directly bear concentrated loads from forklifts, material carts, etc. If unsure about the load, select based on the heaviest possible scenario and reinforce supports and beams separately in heavy-duty areas to ensure long-term use without deformation or damage.

The footrest is an elevated working surface, with drain holes on the plate surface allowing spilled chemicals and rinse water to drain quickly below the plate. The ground should be equipped with anti-corrosion flooring and diversion channels to direct the liquid to collection tanks or wastewater treatment systems, achieving dry-wet separation and clean-pollution diversion. The footrest only addresses anti-slip, anti-corrosion, and leakage issues on the working surface and cannot replace ground corrosion protection and waste liquid collection facilities. During design, ensure smooth integration of plate perforations, ground slope, and diversion channels to prevent liquid accumulation on the plate or ground. Regularly clean the area below the plate, supports, and diversion channels to remove accumulated chemicals and sludge, preventing liquid buildup that could corrode supports and flooring. Promptly repair and clear any damaged flooring or blocked diversion channels to establish a complete path for plate leakage, ground collection, and centralized treatment, avoiding chemical overflow that causes corrosion and safety hazards.

The tread is fixed to the lower support or beam via Overlapping edge and plastic fasteners. The panels overlap and constrain each other, ensuring that the installation, when properly executed, prevents the tread from warping under normal foot traffic. The key is to ensure the support spacing aligns with the tread's allowable span. The fasteners must be installed correctly and in full quantity, with edge and end fastening on both sides of the walkway to eliminate free edges. If the support spacing is too far apart, causing the tread to sag, or if fasteners are missing or loose, warping, sliding, and abnormal noises may occur during walking. In such cases, additional supports and fasteners should be installed. During installation, first secure the support beams and level them, then lay the panels one by one, securing each as it is placed to prevent any panels from Suspended . After installation, inspect the fasteners and Splice for tightness. Address any looseness or missing fasteners promptly to maintain a flat panel surface and prevent tripping hazards due to warping.

PP is acid and alkali resistant, water-absorbent, and rust-proof, offering a longer service life in indoor corrosive environments. Aging primarily results from ultraviolet exposure and prolonged high temperatures. In indoor workshops without direct sunlight and normal temperatures, aging occurs slowly, allowing the platform to be used for extended periods. When installed outdoors or near heat sources, the material gradually becomes brittle and its strength decreases. In such cases, UV-resistant materials should be selected, shading treatment should be applied, and the platform should be kept away from high temperatures. During daily use, platforms with surface cracking, broken reinforcement bars, worn-out anti-slip protrusions, or significant deformation should be replaced promptly. Standardized panels make individual disassembly and replacement convenient without requiring the removal of entire sections. Establish an inspection system, focusing on checking panels in heavy-load areas, corners, and near support structures. Detecting aging signs early and replacing affected panels can prevent damage during foot traffic, ensuring safety.

First, confirm whether the anti-slip bumps are leveled by chemical crystallization or dirt. When crystallization and dirt cover the bumps, the anti-slip performance will significantly decrease. It is necessary to rinse and brush them clean with clean water or appropriate cleaning solutions to restore the height of the bumps. If the working surface has long-term oil pollution, the plastic surface will reduce the coefficient of friction when encountering oil, requiring enhanced oil removal and on-site management, as well as timely cleanup of leaks and spills. For areas with higher anti-slip requirements, long-term moisture, or slopes, deeper and denser anti-slip plates can be selected, or anti-slip surfaces and strips can be added to the tread plates. Anti-slip shoes should also be provided for operators. The edges and finishing areas of the tread plates must also be anti-slip and anti-tripping. After treatment, on-site testing should be conducted to determine if the walking friction has improved. If it still does not meet the requirements, replace the tread plates with higher anti-slip ratings for heavy-duty, wet, and slippery areas. Do not continue using smooth plate surfaces with oil or crystallization.

Both are used for anti-corrosion walkways, but the materials and applicable scenarios differ. PP stair treads are injection molded, acid/alkali resistant, with anti-slip protrusions on the surface, lightweight, and easy to replace individually, making them suitable for electroplating tank edges and personnel walkways on production line sides. GRP grating has high strength, high load-bearing capacity, and is permeable to light and water, making it suitable for large-scale operating platforms and vehicle-accessible areas. However, the cut edges expose fibers, so the corrosion resistance of the resin and aging should be monitored in long-term strong corrosive environments. For pedestrian walkway edges, PP stair treads are economical and lightweight with anti-slip and leak-proof features. Heavy-duty platforms and vehicle-accessible areas can consider GRP grating. When selecting, compare comprehensively based on load, medium, permeability to light and water, and cost-effectiveness. They can also be used in different zones within the same workshop: plastic stair treads for tank edges and GRP grating for concentrated load-bearing platforms, each leveraging their strengths.
