Getting consistent levels in the bedding layer is one of the most critical steps in any paving installation. A bedding surface that varies in depth means the installer has to compensate during laying — which affects the quality of the finished surface and slows the job down. The AZL-EP rails provide the accurate, stable height reference that makes easy and clean screeding possible: set the rails at the required level and the compatible screeding system does the rest. The 13m set is suited to smaller and medium-sized paving areas; for larger projects, the Probst AZL-EP 25m Screeding Rails Set is available.

“The AZL-EP takes the guesswork out of screeding. Set the rails to the required level, connect them together and run the screeding system along them to create a consistent bedding layer. It’s quicker, repeatable and much easier on the operator than trying to achieve the same accuracy by eye.”

The AZL-EP and EP-UNI — A Purpose-Designed Screeding System

The AZL-EP isn’t just a set of metal rails — it’s a guide system designed specifically to work with PROBST’s hand screeding equipment. PROBST designs the AZL-EP rails and the EP-UNI Screeding System to work together as a matched system. The EP-UNI is specifically engineered to run on AZL-EP rails — its aluminium screeding profile is designed not to leave the rails during use, even when working with large quantities of bedding material. The cubical inclined-plane cross-section of the AZL-EP rail joints means it is impossible for the EP-UNI’s wipers to hook into the joints, giving a clean, uninterrupted screeding pass along the full length of the rails.

Together, the two products give contractors a complete hand screeding system: the AZL-EP provides accurate guidance at the correct level, and the EP-UNI delivers a consistent, level bedding surface across the full working width. Using them as PROBST intends — as a system rather than separately — is what produces the consistent paving levels that make laying straightforward.

If you need the EP-UNI screeding tool to go with these rails, it’s available here: Probst EP-UNI Screeding System — 90/230 and 230/300 variants.

Key Benefits for Landscaping and Paving Contractors

• Helps achieve a consistently level bedding layer — the rails give the contractor a fixed guide to screed against, helping create an even, accurate base ready for paving slabs or blocks
• Makes screeding quicker and more straightforward — the integrated plug-in connections allow the rails to be joined quickly, without fiddly separate connectors
• Reduces physical effort — when used with the Probst EP-UNI, the screeding profile runs along the rails, helping contractors maintain a consistent finish without relying solely on manual judgement and effort
• Suited to smaller and medium-sized paving areas — 13m of total rail length across 1.5m and 2.5m sections gives flexibility when setting up screeding runs on domestic and smaller commercial projects
• Built for demanding site conditions — galvanised steel construction provides corrosion resistance and durability for repeated use on landscaping and construction sites
• Stable connections maintain accuracy — the cubical inclined-plane joints align correctly and prevent the screeding tool from catching on the connections, helping maintain a smooth screeding run
• Reusable across multiple jobs — a purpose-designed rail system that can be set up, dismantled and reused, rather than improvising from whatever materials happen to be on site
• Can improve the overall quality of the finished installation — a more consistent bedding layer gives the paving installer a better starting point, making the subsequent laying of blocks or slabs easier and more uniform

Who Uses the Probst AZL-EP Screeding Rails?

Block Paving Contractors

Block paving contractors use the AZL-EP rails to set consistent screeding levels for bedding sand before laying blocks. The rails provide a fixed height reference across the working area, allowing the EP-UNI screeding profile to produce a level, uniform bedding surface. The plug-in assembly means rails can be set up, moved and repositioned quickly as work progresses across the site.

Landscaping & Hard Landscaping Contractors

Landscaping contractors working on patios, paths, terraces and garden paving use the AZL-EP rails where a consistent bedding level needs to be established before laying the surface material. The 13m set suits most domestic and smaller commercial landscaping areas, and the combination of 1.5m and 2.5m rail sections gives flexibility in how the rails are laid out across different-shaped working areas. Rather than improvising screed guides from whatever is available, contractors have a reusable, purpose-designed system that can be set up and dismantled efficiently between areas.

Driveway Installers

For driveway installations, the AZL-EP rails provide a controlled reference level for screeding bedding material across the full working width. Used alongside the EP-UNI 90/230 or EP-UNI 230/300, the system gives driveway installers a repeatable, consistent screeding setup that can be moved and reset as each section of the driveway is prepared.

Patio & Paving Contractors

For patio and general paving installations, the AZL-EP rails are our recommended guide rail system for setting bedding levels before laying paving slabs. The galvanised steel construction means the rails can be used repeatedly across multiple projects without corroding, and the plug-in connectors make set-up straightforward on site.

Why Use Dedicated Screeding Rails Instead of Improvised Guides?

Setting a consistent bedding level is one of the most important steps in any paving installation. If the screeded surface varies in height, the paving installer has to compensate during laying, which affects the finished result and slows the job down.

Improvised methods — lengths of timber, copper pipe, or whatever happens to be on site — can work for a single run but are difficult to hold at a consistent height and can flex or move under the weight of the screeding tool. Purpose-built screeding rails like the AZL-EP give a rigid, stable height reference that stays in position during use.

The AZL-EP rail joints use a cubical inclined-plane cross-section that creates inclined rail joints in each direction. This means the wipers on compatible PROBST screeding tools cannot hook into the rail joints during use, giving a clean, uninterrupted screeding pass. That’s a detail that improvised guide rails simply cannot replicate.

Frequently Asked Questions about the Probst AZL-EP 13m Screeding Rails

I’m Cleo, owner of The Paving Experts, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. I work alongside a small team of incredibly knowledgeable and caring individuals who share the same passion for getting it right. The FAQ answers below come from the questions we’re asked every single day.

What is the Probst AZL-EP Screeding Rails Set?

The Probst AZL-EP is a professional galvanised steel screeding guide rail system designed to provide accurate guidance for PROBST hand screeding systems. When set at the required level, the rails allow easy and clean screeding of bedding material across the working area — giving contractors a consistent, accurate reference for the EP-UNI aluminium screeding profile to run along before paving is laid.

What is included in the 13m AZL-EP set?

The 13m set includes 2 × 1.5m and 4 × 2.5m galvanised steel rails, giving a total of 13 metres of screeding rail. Total weight is 22kg.

What is the difference between the 13m and 25m AZL-EP sets?

The 13m set contains 6 sections (2 × 1.5m and 4 × 2.5m) and weighs 22kg. The 25m set contains 10 sections (2 × 1.5m, 4 × 2.5m and 4 × 3.0m) and weighs 41kg. The 13m set is suited to smaller and medium-sized paving areas; the 25m set is for larger paving projects. The rail material, pipe diameter, connection system and method of use are the same across both sets.

What screeding systems are compatible with the AZL-EP rails?

The AZL-EP is PROBST’s dedicated screeding rail kit for the EASYPLAN EP-UNI, TELEPLAN-TP and FIXPLAN FP hand screeding systems. For the EP-UNI specifically, the rails provide the height reference that the EP-UNI aluminium screeding profile runs along during use.

Why are the AZL-EP rails and the EP-UNI used together?

PROBST designs the AZL-EP rails and the EP-UNI as a matched system. The EP-UNI screeding profile is engineered to run on AZL-EP rails and stay in contact with them throughout the screeding pass. The cubical inclined-plane rail joints make it impossible for the EP-UNI’s wipers to catch on the joints, giving a clean, uninterrupted pass. Used together, they provide the accurate guidance and consistent levels that make easy and clean screeding possible.

What is the difference between AZL and AZL-EP screeding rails?

These are two different PROBST screeding rail systems for different tools. The AZL uses a special aluminium profile and is designed for the PROBST TAK and TAS-UNI screeding systems. The AZL-EP uses galvanised steel pipes (26.9mm diameter) and is the dedicated rail kit for the EASYPLAN EP-UNI, TELEPLAN-TP and FIXPLAN FP. If you’re using the EP-UNI, you need the AZL-EP.

What are AZL-EP rails made from?

The AZL-EP rails are made from galvanised steel pipe with a diameter of 26.9mm (1 inch). The galvanised finish makes them non-corroding and suitable for repeated use on site.

How do AZL-EP screeding rails connect together?

The sections connect using an integrated plug-in system. The connection is non-detachable and allows rail sections to be joined quickly and securely without any additional fixings or tools.

Do the rail joints interfere with the screeding tool?

No — and this is one of the key design features of the AZL-EP. The cubical inclined-plane cross-section creates inclined joints in each direction, making it impossible for the wipers on PROBST’s compatible hand screeding systems to hook into the joints during use. This gives a clean, uninterrupted screeding pass along the full length of the rails.

Do the AZL-EP rails corrode?

No. The rails are made from galvanised steel pipe and are non-corroding — suitable for repeated on-site use without rusting.

Can the AZL-EP rails be repositioned during a project?

Yes. Once a section has been screeded and paving laid, the rails can be removed, repositioned and reset for the next section. The plug-in system makes this quick without any tools.

How do you set screeding rails for block paving?

Set the AZL-EP rails at the required bedding depth below the finished paving level, checking with a spirit level or string line. Position them parallel to each other at the correct spacing for the EP-UNI working width, ensure they are stable, then use the EP-UNI to screed the bedding sand to the level set by the rails.

Is the 13m set suitable for domestic paving projects?

Yes. The 13m set is well suited to domestic projects such as patios, garden paths and smaller driveways. For larger domestic or commercial paving areas, the 25m set may be more appropriate.

Is free delivery included?

Yes — the Probst AZL-EP 13m Screeding Rails Set includes FREE delivery.
