Floor Springs for Heavy Pivot Doors: 300kg to 600kg

Updated 2026-11-09 · RAYEN 雷茵

What counts as a heavy pivot door here?

Anything past the 200kg ceiling of our hinges and overhead closers. Large entrance doors in solid timber, clad steel or stone veneer often get there. At that weight the door hangs from the floor spring and turns on a top pivot, with no hinges on the edge.

What should you measure?

• Door weight. Weigh one, or take the door maker's figure for the finished leaf, cladding included.
• Door thickness. Every model here needs ≥60mm.
• Width from the turning line to the door edge.
• Pivot position: edge, offset or centre. See edge, offset or centre pivot.
• Whether the door must close at a set speed, or simply return and hold open.

The heavy end of the range

The chart lists every floor spring by weight. The heavy models sit at the bottom.

• D-1067: edge pivot, 200kg at ≤1350mm or 300kg at ≤1500mm, EN6/EN7, two-stage valve.
• D-1068: offset pivot, the same ratings as D-1067.
• DZ-2039: centre pivot, 300kg at ≤1250mm or 400kg at ≤1350mm, EN5/EN6, two-stage valve.
• D-3002: edge pivot, 300kg at ≤1350mm or 500kg at ≤1500mm. No closing valve or closing force is listed.
• D-3001: offset or centre pivot, 400kg at ≤1200mm or 600kg at ≤1350mm. No closing valve or closing force is listed. It reads 360° opening.

All of them are in 45# steel, in satin stainless or matt black, and hold open at 90°.

Speed control or weight?

This is the real decision. Up to 400kg you can have the two-stage closing valve. Past 400kg you get the load, but the listing shows no valve to set the closing speed on site.

If the brief says the door must close slowly, stay at or under 400kg with DZ-2039, or 300kg with D-1067 or D-1068. If the door is heavier, talk to us about the door before you design around a slow close.

What about the top of the door?

Every floor spring needs a top pivot on the same line as its spindle. Our top pivots are listed by body size, from D-3021 at 138mm long to D-3019 at 180mm. No load figure is printed for them, so on a door this heavy we confirm the top pivot against the floor spring and your door section. See top pivots and patches.

A worked example

A villa entrance has a 70mm oak pivot door at 350kg, 1300mm from the turning line to the edge, on an offset pivot.

• D-1068.300 stops at 300kg, so it fails on weight.
• D-3001.400 carries the weight but stops at ≤1200mm. D-3001.600 carries 600kg at ≤1350mm, so it fits.
• On a centre pivot, DZ-2039.400 would also fit, at 400kg and ≤1350mm, and it adds the closing valve.

So if the architect can accept a centre pivot, the door gets speed control. If the offset position is fixed, D-3001.600 carries it, and the closing speed is a question to settle with us before the order.

Which finish?

The heavy floor springs and the top pivots both come in satin stainless or matt black. The top pivots are 304 stainless. Match the finish to the top pivot and to the door's other hardware, and give one finish for the whole set on the order.

What is the next step?

Send the door drawing to [email protected], with the weight, thickness, turning line and finish, and we return the floor spring and top pivot drawings to check against your floor and door head. For a quick answer on whether a door is possible, WhatsApp the factory owner. The number is on the contact page. The floor spring selector filters the range by weight and width.
