The Different Types of Ladders and Their Uses

Ladders are designed for specific tasks, working heights and conditions. Choosing the right ladder helps you work more safely, reach the required height, and avoid using equipment that is unsuitable for the job.

BPS Depot offers a practical range of ladder types for household, trade, and commercial use. From compact step ladders to extension ladders for roof access, each design has its own strengths.

This guide explains the different types of ladders, their main benefits, and the jobs they are best suited to. It also covers ladder height, materials, duty ratings, and key safety features to consider before buying.

Choosing the Right Ladder for the Job

Before comparing ladder types, think about where the ladder will be used, how high you need to reach and how long the task is likely to take. A ladder that is suitable for basic tasks such as changing light bulbs may not be safe for cleaning gutters or carrying out roof work.

Consider the surface beneath the ladder. Step ladders and platform ladders need firm, level ground and are not suitable for uneven surfaces unless designed for them.

The total weight placed on the ladder matters as well. This includes the user, clothing, tools, and any materials being carried. Always check the ladder’s duty rating and maximum weight capacity before use.

For prolonged tasks or extensive movement, scaffolding or a mobile elevated work platform may be more appropriate.

Which Ladder Material Is Best?

Aluminium ladders are lightweight, durable and easy to carry. They are suitable for many general household, decorating and maintenance tasks.

Fibreglass ladders are the safer choice when working near electrical wires, power lines or other electrical sources because fibreglass is non-conductive. Electricians often prefer this material for electrical work.

Wooden ladders can also offer non-conductive properties when they are clean and dry, but they tend to be heavier and require more maintenance than aluminium or fibreglass options.

The right material depends on the task, environment and electrical hazards present.

Understanding Ladder Ratings

Duty ratings indicate the maximum safe load a ladder can support. The rating must include the user’s weight as well as tools, equipment and materials. Do not assume a tall ladder has a higher load capacity. Always check the product specification. Using a ladder beyond its rated capacity can damage the rungs, rails or locking mechanisms and may cause the ladder to fail.

What Are the Different Types of Ladders?

The different types of ladders include step ladders, extension ladders, platform ladders, combination ladders, trestle ladders and telescopic ladders. Each one is designed around a different way of working at height.

Some are self-supporting, while others must lean against a wall. Multi-position ladders can change shape for varied tasks, stairs or different heights.

Step Ladders

Step ladders have an A-frame shape and open on four legs, allowing them to stand without support from a wall. Their self-supporting design makes them suitable for indoor and outdoor tasks on firm, level ground.

Step ladders range from just over 1m to almost 4m. Smaller models can work as a step stool, while larger options reach ceilings and fixtures.

Pros:

• Stable design: The A-frame structure creates a broad base when all four legs are positioned correctly.
• Easy to move: Most models use lightweight material, making them simple to carry between rooms or work areas.
• Convenient storage: Folding designs take up less storage space.
• Versatile access: They are useful where a leaning ladder cannot be supported against a wall.

Uses:

• Household tasks: Reaching a kitchen cupboard, changing lightbulbs and accessing the top shelf.
• Painting walls: Suitable for decorating and other work at modest heights.
• Retail and stockrooms: Useful for reaching high shelves and arranging stock.
• Garden maintenance: Can assist with light trimming tasks when placed on a level, stable surface.

Step ladders are not suitable for uneven ground because all four legs must remain secure. Never stand on the top step unless the ladder is specifically designed to allow it.

Extension Ladders

Extension ladders are made from two or more sliding sections that can be easily extended to reach greater heights. They require support from a wall, roof edge or another stable vertical surface.

Typical models reach 2.2m to 5.5m, while specialist roof ladders can extend beyond 7m. Most are made from lightweight aluminium.

Pros:

• Greater reach: Ideal for work above the height offered by most step ladders.
• Adjustable height: Sections can be extended to suit different access requirements.
• Slip-resistant features: Many models include textured rungs and secure feet.
• Transportable design: Retractable sections make them shorter to carry than a straight ladder of the same working height.

Uses:

• Cleaning gutters: Provides access to rooflines and upper exterior areas.
• Roof work: Useful for gaining access to a roof when set up correctly.
• Window cleaning: Suitable for reaching upper-storey glazed windows.
• Exterior painting: Helps decorators access higher sections of a wall.

Extension ladders should be set at a 4:1 angle, with the base one unit from the wall for every four units of vertical height. Position the ladder on firm ground.

Platform Ladders

Platform ladders provide a large, flat standing area at the upper working level. Many also include a guard rail or frame that gives the user additional support.

They usually range from 2m to 4m tall and are made from aluminium, fibreglass or steel. Platform ladders provide greater comfort for tasks requiring both hands.

Pros:

• Stable working platform: The user can stand more comfortably than on a narrow rung.
• Hands-free working: Tools or small materials can often be stored on the platform or tray.
• Improved comfort: Useful for longer periods of light maintenance and decorating.
• Indoor and outdoor use: Suitable for varied tasks when placed on a firm surface.

Uses:

• Decorating: Helpful for painting walls and ceilings.
• Maintenance: Suitable for repairing fixtures and changing light bulbs.
• Warehouses and workshops: Useful for reaching equipment or high shelves.
• Installation work: Provides a steady position for jobs requiring both hands.

The platform should never be overloaded with tools. Check the total weight against the ladder’s duty rating before climbing.

Combination Ladders

Combination ladders are multi-purpose ladders that can be configured into several positions. Depending on the design, they may function as a step ladder, straight ladder, extension ladder or stairwell ladder.

Many can form three different structures and reach around 3 metres when fully extended. They are commonly made from aluminium or fibreglass.

Pros:

• Multiple positions: One ladder can support several different functions.
• Adjustable height: Useful for jobs that require access at different heights.
• Space saving: A single product may replace two or more other ladders.
• Good value: Suitable for users who complete varied tasks around the home or workplace.

Uses:

• Home improvement: Useful for painting, decorating, repairs and fitting fixtures.
• Stair work: Some multi-position ladders can be adjusted for use on stairs.
• Commercial maintenance: Helpful when the exact working arrangement may change throughout the day.
• Garden tasks: Can be adapted for different access needs where the surface is level.

Combination ladders can have a lower maximum weight capacity than some extension ladders. Check every hinge and locking point before use and confirm that all sections are fully secured.

Trestle Ladders

A trestle ladder is a self-supporting ladder with access on both sides. Some are designed for two people to work from opposite sides, although this should only be done when the manufacturer specifically permits dual use. The wide base provides strong support when all four legs are level.

Pros:

• Access from both sides: Useful when a task involves two work positions.
• Strong foundation: The broad stance creates stability on a suitable surface.
• Efficient teamwork: Approved dual-use models can support a second person.
• Practical for trade work: Useful for decorators, cleaners and maintenance teams.

Uses:

• Home projects for two: Suitable for jobs where a second person needs to work at the same height.
• Commercial decorating: Useful for painting or finishing larger areas.
• Temporary work platforms: Some trestles can support a suitable staging platform when used as instructed.
• Workshop access: Provides convenient access from either side.

Always confirm whether the model is rated for two users. Their combined body weight, tools and equipment must remain within the stated maximum weight capacity.

Telescopic Ladders

A telescopic ladder, sometimes called a telescoping ladder, extends rung by rung and collapses into a compact unit. It offers the reach of a taller ladder without requiring as much storage space. Many extend beyond 4 metres and use lightweight aluminium. They suit indoor and outdoor maintenance when locked correctly.

Pros:

• Compact storage: The ladder collapses fully and can fit into smaller storage areas.
• Easy transport: Its reduced size makes it convenient to carry in a vehicle.
• Customisable height: Users can select the required extension for the task.
• Versatile access: Suitable for several maintenance and inspection jobs.

Uses:

• Loft and attic access: Helpful where a permanent loft ladder is not fitted.
• Indoor maintenance: Suitable for reaching high ceilings or fixtures.
• Outdoor repairs: Useful for light work around walls, roofs and gutters.
• Mobile trades: Convenient for workers who need a ladder that is easy to carry.

Each rung must lock securely before use. Incorrect set-up can cause sections to retract, so inspect the locking indicators and follow the manufacturer’s instructions.

Ladder Safety Essentials

Inspect ladders before each use for cracked rungs, bent rails, damaged feet, loose hinges or faulty locks. Do not use a damaged ladder.

Maintain three points of contact while climbing. This means two hands and one foot, or two feet and one hand, remain in contact with the ladder. Avoid carrying heavy or awkward items while climbing. Use a tool belt or hoist line where possible.

Keep metal ladders away from electrical wires and power lines. Use a non-conductive fibreglass ladder when working near electrical hazards. Never place a ladder on boxes, loose boards or unstable objects to gain extra height. Select the correct ladder height instead.
