Cutting and Measuring Metal Profiles for Railings: Our Process

t320-18

Railing profiles are cut from measurements taken on site, using a written drawing that defines every length, angle and joint before any metal is touched. Precision comes from careful measuring, accurate saw setup and checking each cut against the drawing before welding and finishing.

Why Accurate Measurement Comes First

Every railing starts on the balcony itself, not in the workshop. We measure the opening length, the height from the floor to the top rail, the slab edge, and any wall returns or corners. Small differences matter, because a railing that is off by a few millimetres will show at every joint and make the installation harder.

We record measurements in a simple drawing and mark which values were taken from the slab edge and which from the finished floor, so the fabrication team knows exactly what each number refers to.

Planning the Profile Layout

Before cutting, the profile layout is drawn to scale. This shows the top and bottom rails, the vertical posts or infill, the spacing and the connection points. Planning on paper helps us spot awkward corners and decide where a joint should sit so it stays clean and easy to finish.

Cutting Profiles to Length and Angle

Profiles are cut on calibrated saws set to the angles from the drawing. For a corner or a rake along a staircase, the angle is set carefully and checked with a protractor or a test cut on scrap material. Cutting slowly and keeping the material firmly clamped reduces burrs and keeps the cut square.

Each finished piece is compared against the drawing before it moves to the next stage. Catching an error here is far cheaper than fixing it after welding.

Assembly, Jigs and Quality Checks

For repeatable joints we use simple jigs and reference surfaces. The pieces are tacked together, checked for square and alignment, and then fully welded. Heat can shift thin steel, so we check dimensions again after welding and before finishing.

What We Check

Overall length, the height of the railing, the straightness of the top rail, the gap at each joint and the position of fixing holes. Railing heights and infill spacing should follow the Israeli railing standard SI 1142; exact values are confirmed with the engineer for each project.

Finishing and Protection

Once the railing is assembled, it is ground smooth at joints and then protected. Depending on the project, this can be hot-dip galvanizing followed by powder coating, which gives a durable finish suited to outdoor balconies and the coastal Tel Aviv climate. Finishing is done after assembly so that the coating covers the welds evenly.

On-Site Installation

On installation day, the railing is fixed to the slab or wall using the anchor points planned in advance. Because the railing was measured on site and cut to the drawing, the fit is usually straightforward. We check level and plumb as we fix, then confirm the final alignment before leaving the balcony.

If anything on site differs from the drawing, we stop and adjust the plan together with the client, rather than forcing the piece into place.

Frequently asked questions

Why does the railing need to be measured on site instead of from plans?

Plans show the intended build, but walls, slabs and finishes often vary by a few millimetres. Measuring on site means the railing fits the real balcony.

How precise are the angle cuts on railing profiles?

Angles are set on calibrated equipment and checked with test cuts and the drawing. Final accuracy is confirmed by fit-up before welding.

Can a railing be changed after the measurements are taken?

Small changes can often be made before cutting. Once profiles are cut or welded, changes become costly, so we confirm the design with you first.

Does the finish affect the fit of the railing?

Yes. Galvanizing and powder coating add a thin layer, so we account for it in the planning and check dimensions after finishing where needed.

Common mistakes to avoid

Relying on old plans without re-measuring the balcony is the most common error. Cutting before confirming the angles and heights leads to pieces that do not fit.

Our recommendation

Measure at least twice, record which surface each number refers to, and ask for a written drawing to approve before production starts.

Summary

Accurate railings come from careful site measurement, a clear drawing, precise cutting and angle checks, and fit-up before finishing and installation.
