We bring
flexibility
to life

We have been manufacturing steel springs since 1978. From 0.20 mm to 40 mm wire diameter, we coil the springs agricultural machinery needs — from balers to seed drills, from combine harvesters to hay rakes.

Spring calculator

Enter the dimensions, let us see the spring together

Change the values for four spring types: we calculate the spring rate, solid length and spring index instantly. The index is the best indicator of manufacturability — if you go outside the limits, we will tell you.

Compression spring — parameters TS EN 13906
Agricultural presets
Assessment

The calculation is for preliminary assessment and assumes closed-and-ground ends. Binding values are confirmed with a sample and approved technical drawing.

Production flow

From wire to shipment, nothing outsourced

Every step after coiling happens in our own plant. This shortens lead times and keeps quality responsibility in one pair of hands.

01 · Coiling

CNC spring coiling

Formed in the 0.20–40 mm wire range.

02 · Heat treatment

Tempering

Stress is relieved and elasticity becomes permanent.

03 · Grinding

End grinding

Seating faces are flattened on compression springs.

04 · Coating

Galvanizing

Surface protection against corrosion.

05 · Shipping

Packaging

Domestic and international logistics included.

Company

From one workshop
to 47 years

Metiş Yay was founded in 1978 by Mehmet Ertuğrul in a small workshop. Growing quickly on the strength of its quality, it was incorporated in 1998; with an experienced team and a continuously renewed machine park it has reached a daily capacity of 900,000 units.

"Success and continuity in manufacturing are secured by honesty and quality in service."

Met-İş is incorporated; production volume and machine park grow.

Today

Capacity of 900,000 units per day; domestic and international shipping to five industries.

FAQ

What people ask before requesting a quote

The eight questions we are asked most on the phone. If yours is not here, write through the form — we reply the same day.

Can you make a spring that is not in the catalogue?

Yes. The catalogue is a list of frequently requested items, not the limit of what we make. Because our coiling line works without tooling dependency, we can produce from a sample, a technical drawing, or simply a photograph of the old spring.

What wire diameter range do you work in?

Between 0.20 mm and 40 mm. That range covers everything from electronic contact springs to heavy-duty cultivator springs.

I do not know the dimensions — can I still get a quote?

You can. The machine brand, model and where the part works is usually enough. For uncertain items, a photograph of the old spring next to a ruler does the job.

Are heat treatment and coating outsourced?

No. Coiling, tempering, end grinding, galvanizing and packaging all happen in our own plant. This shortens lead times and keeps quality responsibility in one pair of hands.

Are the spring calculator results binding?

The calculator is for preliminary assessment: it gives the spring rate, solid length and spring index using TS EN 13906 relations. Material strength values are typical values; final production is confirmed against the actual figures in the wire supplier's certificate.

Which industries do you manufacture for?

Agricultural machinery makes up the bulk of our catalogue. Alongside that we manufacture for the appliance and electronics, automotive, defence and toy industries.

Do you ship internationally?

Yes. Packaging and logistics are handled in our own plant; we ship both domestically and internationally.

How are order quantity and lead time determined?

Both depend on the size of the product, the coating type and the current production schedule. Send us the item and quantity through the quote form and we will give you exact figures.
