6063 aluminum
A medium-strength 6000-series alloy prized for excellent extrudability, a smooth surface, and strong corrosion resistance. It is the most common alloy for anodized telescopic and pool poles.

Glossary
Aluminum Alloys & Tempers
6061 aluminum
A stronger structural alloy (about 310 MPa tensile) with good corrosion resistance and weldability, used where a pole needs extra strength or stiffness.
Billet
The solid cylindrical aluminum bar that is heated and pushed through a die to form extruded tubes and profiles.
- 6005 aluminum
- A medium-to-high-strength 6000-series alloy balancing strength and extrudability, used for sturdier poles and structural profiles.
- 7075 aluminum
- A 7000-series alloy with very high strength (about 572 MPa) but lower corrosion resistance and harder extrusion and anodizing; rarely needed for poles.
- Temper (T5 / T6)
- The heat-treatment condition of an alloy. T5 is cooled and artificially aged after extrusion; T6 is solution heat-treated then aged for higher strength.
Glossary
Tube & Pole Dimensions
Wall thickness
The thickness of the tube wall, commonly 0.8 to 1.5 mm for poles. It strongly affects strength and weight.
Wall thickness vs strength
For telescopic poles, wall thickness and diameter usually affect rigidity more than the alloy grade itself.
Sections
The number of nesting tubes in a telescopic pole. More sections add reach but also add joints to lock and align.
- Outer diameter (OD)
- The external diameter of a pole tube. A larger OD increases rigidity and load capacity.
- Inner diameter (ID)
- The internal diameter of a tube. The gap between one section's OD and the next section's ID sets the telescoping fit.
- Collapsed length
- The length of a telescopic pole fully retracted. A shorter collapsed length improves carton and container packing density.
- Extended length
- The maximum usable length when the pole is fully opened.
- Tolerance
- The allowed deviation in a dimension, for example plus or minus 0.05 mm. Tight tolerance gives a smooth slide without wobble.
- Straightness
- How straight a tube runs along its length. Poor straightness causes binding and a visible bend.
Glossary
Locks & Mechanisms
Flip lock (cam lock)
An external lever clamp that locks sections quickly and holds high loads.
flip-lock poles →
Twist lock
An internal expander activated by twisting adjacent sections; simple and low-cost.
twist-lock poles →
Push-button lock
A spring-loaded pin that snaps into pre-set holes to fix the pole at specific lengths.
push-button poles →- Telescopic pole
- A pole made of nested tube sections that slide and lock to adjust length in a single unit.
- Threaded connection
- Screw-together sections used on add-on extension poles for long, static reach.
- End cap / plug
- The fitting that closes a tube end, protects the user, and can carry the lock or an accessory thread.
Glossary
Surface Finishing
Anodizing
An electrochemical process that grows a hard, corrosion-resistant oxide layer on aluminum, often colored. It is the standard finish for poles.
anodizing service →
Sandblasting
Blasting the surface with abrasive to create a uniform matte texture, often before anodizing.
Powder coating
A dry paint finish applied electrostatically and baked on. It offers many colors but less abrasion resistance than anodizing on sliding poles.
- Hard anodizing
- A thicker, harder anodized layer that adds extra wear and corrosion resistance.
- Coating thickness
- The anodize layer depth, measured in microns. Poles are commonly finished at 12 to 15 microns.
Glossary
Manufacturing & OEM
Aluminum extrusion
Forcing heated billet through a shaped steel die to produce tubes and profiles.
production capacity →
DFM (Design for Manufacturing)
Reviewing a design for cost-effective, reliable production before tooling is cut.
OEM
Original Equipment Manufacturer: producing a product to the buyer's own specification.
OEM service →- Press tonnage
- The force rating of an extrusion press, for example 350T to 2000T. Larger profiles require higher tonnage.
- Tooling / die
- The hardened steel die that shapes an extruded profile. Custom shapes need dedicated tooling.
- ODM
- Original Design Manufacturer: the factory designs the product, which the buyer then brands.
- Private label
- Producing goods under the buyer's brand, artwork, and packaging. private label →
- MOQ
- Minimum Order Quantity, the smallest order a factory will run, typically 500 to 1,000 units per SKU here.
- Sample lead time
- The time to make an evaluation sample, about 7 to 10 days for a custom pole.
- Mass-production lead time
- The time to produce a full order after sample approval, about 25 to 35 days.
- Batch traceability
- Linking each shipment to its material and production records for quality control and recall management. batch traceability →
Glossary
Quality & Testing
Salt spray test (ASTM B117)
A standardized corrosion test that exposes parts to salt fog for a set number of hours, such as 500 or more.
AQL
Acceptable Quality Limit, the sampling standard used for pre-shipment inspection, for example AQL 1.5.
quality assurance →
IATF 16949
An automotive-grade quality-management standard that signals tight process control.
- Mill certificate (EN 10204)
- A document certifying an alloy's chemical and mechanical properties as supplied by the mill.
- ISO 9001
- The international standard for quality management systems. certifications →
