All-Weather Durable Auto Running Boards

-- Steady & Reliable Manufacturer --

Technical Overview

All-Weather Durable Running Boards are engineered to maintain reliable function across a wide spectrum of environmental extremes, ranging from sub-zero winters to dusty desert heat. Key to this performance is the use of temperature-compensated motor lubricants and hermetically sealed motor units (IP68). The mechanical linkage features open architecture to shed ice and debris easily, while pivot points are protected by sealed roller bearings that resist contamination.

Corrosion defense is maximized through a Triple-Layer Coating System (E-Coat, Zinc-Primer, and Heavy-Duty Powder Coat) on all steel components. The step surface features a non-porous, high-grip texture designed to resist moisture accumulation and freezing.

Introduction

Vehicle accessories operating in extreme conditions—whether exposed to road salt, high humidity, freezing temperatures, or persistent dust—require engineering beyond standard specifications. These all-weather steps are built with specialized materials and sealing processes to ensure reliable, year-round functionality, minimizing the need for seasonal maintenance.

Bohai Automotive Technology Co., Ltd. specializes in environmental resilience. Our internal testing procedures simulate the toughest global climates, allowing us to specify components and finishes that deliver predictable performance regardless of geographical challenges.

Applications

Cold Climate Regions (e.g., Russia, Canada, Scandinavia): Essential for resisting corrosion from road salt and ensuring reliable function in freezing temperatures.
Coastal and High-Humidity Regions: The advanced coating systems protect against salt air and pervasive moisture degradation.
Mining, Oil, and Gas Utility Vehicles: Operating reliably in environments where exposure to chemicals, extreme dust, and constant vibration is common.
Off-Grid/Exploration Vehicles: Required for reliability where immediate repair or component replacement is difficult.

Common Questions

Q: What is the benefit of the synthetic, temperature-compensated motor lubricant?
A: Synthetic lubricants maintain a consistent viscosity across a wide temperature range. This ensures that the motor torque is not excessively drained by thick, cold grease in winter, or by thin, ineffective grease in hot desert climates.

Q: How does the system prevent ice build-up in the winter?
A: The open linkage geometry allows ice and snow to fall away easily. Furthermore, the motor's initial high-torque surge is specified to break apart any thin ice layer that may form around the stowed step.

Q: Is the coating system resistant to harsh chemical car washes?
A: Yes. The heavy-duty powder coat and underlying E-coat are chemically resistant to the common road grime removers, detergents, and acidic pre-washes used in commercial car washes.

Core Features

Thermal Reliability: Specialized lubricants and thermally stable electronic components ensure consistent deployment speed and torque delivery across extreme temperature fluctuations.
Maximized Corrosion Defense: The three-stage coating system provides a nearly impenetrable barrier against water, road salts, and chemical solvents.
Contamination Proof: IP68 sealing prevents the ingress of fine dust, sand, and water, protecting the motor and electronics from degradation.
Debris Shedding Linkage: The mechanical design minimizes pockets and shelves where snow, ice, or mud can accumulate and freeze, ensuring free movement.

Manufacturing & Customization

Manufacturing includes mandatory Environmental Chamber Testing of sample assemblies to verify functional performance at the extreme ends of the specified temperature range. Motors are Leak-Tested under submerged pressure to confirm the IP68 rating.

Customization Opportunities: Focused on environmental needs:

Cold-Weather Heating Pads: Integrating low-voltage, self-regulating heating elements into the step platform to prevent heavy ice accumulation in ultra-cold markets.
Dust-Proof Air Filtration: Offering a specialized motor enclosure with filtered air vents for extreme dusty environments (e.g., Australia, Middle East) to prevent internal abrasive wear.
Emergency Lighting Integration: Developing step lighting that can be integrated with external emergency or warning light systems for utility vehicle use.

Material Selection

Structural components use Q345 Steel and 6061 Aluminum, with all contact surfaces managed for Galvanic Isolation.

Seals and gaskets are made from EPDM Rubber or High-Grade Silicone, specifically chosen for flexibility and resistance to degradation in both extreme heat and UV exposure.

All wiring utilizes TPE (Thermoplastic Elastomer) jacketing, providing superior chemical and abrasion resistance compared to standard PVC in harsh undercarriage environments.
