Adjustable plastic base is widely used in floor laying, roof platform, garden landscaping, outdoor terrace and industrial tripod. It is height adjustable, strong load-bearing, corrosion-resistant and easy to install, especially suitable for uneven ground or scenes that require quick installation.
Basic composition of adjustable plastic base
Base Plate
It is the lowest part of the base system that contacts the ground;
The design is usually a reinforced rib structure or a porous disc;
Its function is to increase the contact area with the ground, improve stability, and prevent sinking or sliding.
Threaded Riser/Adjustable Shaft
The height can be adjusted by rotating;
The interior is usually threaded and engages with the top cover and chassis;
The height adjustment range is from 30mm to 1000mm, depending on the model.
Top Plate/Head
Directly in contact with the load-bearing objects such as floor, tiles or wooden grilles;
Designed with different slots and gaskets to facilitate the installation of different sizes and materials;
Some models are equipped with non-slip rubber pads or sound insulation pads to enhance friction and comfort.
Shims or Joist Holders
Used to fine-tune height differences and unevenness;
Some products are equipped with wooden keel clamps, tile gap adjusters, etc., supporting multiple installation methods.
Height limiter or locking ring (Locking Ring)
Prevents the base from rotating under load or vibration;
Ensures long-term stability of the structure.
Material characteristics
The adjustable plastic base is mainly made of engineering-grade high-strength polypropylene (PP) or modified polyethylene (HDPE), and has the following characteristics:
Strong corrosion resistance: suitable for harsh environments such as outdoor, high humidity, and high salt;
High compressive strength: the bearing capacity of a single base is generally above 500kg, and the high-strength type can reach more than 1000kg;
Good weather resistance: can work stably in the range of -40℃ to +80℃;
Environmentally friendly and recyclable: the material is non-toxic and harmless, and the green construction is in line with the concept of sustainability.
Core functions and performance advantages
Structural load-bearing: High-quality plastic bases can bear hundreds of kilograms of vertical pressure, meeting the needs of laying a variety of materials such as large platforms, wooden floors, tiles, metal plates, etc. Some industrial-grade products can even be used for primary support of mechanical equipment.
Fast construction: Its modular structure simplifies the construction steps, does not require cement pouring or welding brackets, saves manpower and material resources, and greatly shortens the construction period.
Ground protection: The bases are all designed with large-area contact plates to effectively disperse ground stress, suitable for waterproofing membranes, roof membranes, and ecological layers, without damaging the original structure of the ground.
Ventilation and drainage: Ventilation gaps are left between the structures to help the water vapor flow on the ground, prevent water accumulation, and are conducive to outdoor anti-corrosion, anti-slip and anti-mildew.
Auxiliary sound insulation: Some bases are equipped with rubber shock-absorbing pads on the top to effectively absorb footsteps and structural noise, especially suitable for residential terraces and commercial roof platforms.
Performance Advantage Analysis
High adaptability; specification heights range from 20mm to 1000mm, covering low-level platforms to high-level structures;
High adaptability to terrain; can adapt to slightly uneven terrain; the gasket system can flexibly compensate for the foundation drop; accurate leveling can also be achieved on slopes and step structures.
Wide climate adaptability; the material is UV-resistant and not easy to age; strong temperature resistance, suitable for high-cold or high-temperature areas; moisture-proof and rust-proof, no metal corrosion risk.
High compatibility; can be matched with different surface layers such as wooden keels, metal grilles, stone tiles, etc.; special models support the passage of hidden projects such as lights, cables, and water pipes for easy maintenance.
Environmentally friendly and recyclable; the material is green and recyclable; there is no dust, no noise, no wet operation during the installation process, which is green and environmentally friendly; it can be reused after disassembly to reduce waste.
How to choose the right adjustable plastic base and installation points
Choose according to load-bearing requirements
Does the project have heavy-load requirements? For example, landscape platforms and roof gardens generally have low load-bearing requirements, but industrial platforms and exhibition structures require high load-bearing capacity.
Standard load-bearing: ≥400kg
Reinforced load-bearing: ≥1000kg
Industrial heavy-duty: ≥2000kg (with steel columns or metal plates)
Select functional parts according to ground conditions
If the ground slope is large: choose a self-leveling base;
For stone laying: it is recommended to use cross strips and gaskets;
Noise-prone areas: rubber shock-absorbing pads are recommended;
Cable pipelines need to be hidden: use a pipeline through-hole structure.
