How This Park Bench Is Fabricated and Checked

A park bench is a galvanized steel frame carrying slats, and the details that decide whether it survives are at the interfaces: between the slat and the frame, between two different metals, and between the bench and the ground it stands on.

The frame is welded in a fixture before galvanizing, and the slat fixings are isolated where the two metals meet – see welding.

Changes Park Bench Metal Fabrication Can Absorb Without New Tooling

The bench is a welded frame with slats, so dimensions and slat layout are open. Changes to the material mix are the ones to discuss early.

Questions Buyers Ask About Park Bench Metal Fabrication

Why wood-plastic composite rather than timber?

Wood-plastic composite does not absorb water, does not split along a fixing and does not need re-oiling or staining, which matters for a bench that will be maintained by a parks department with limited time. What it does do is move with temperature, more than timber, and it is less stiff. So the fixing has to allow for movement – slotted holes rather than round ones – and the slat spacing has to account for the fact that a composite slat will deflect more under the same load. Both of those are design details rather than problems, but they have to be designed in from the start. If your market prefers timber or aluminium, all three are workable and the fixing detail changes with the choice.

How are the slats fixed to a galvanized frame?

With stainless fasteners and a barrier between the two metals. Stainless is the right choice because it will not itself corrode at the fixing, but stainless and zinc are still a couple, and in wet conditions the zinc will sacrifice itself at the contact point and the coating will disappear around the fixing. An isolating washer or a plastic sleeve at the contact point prevents that, and it is a small cost that decides whether the fixings are still tight in five years or have become the rust spots on an otherwise sound frame.

What does the 300 kg figure cover?

It is the rated static load, and a public bench sees more than static load. In practice the demanding cases are people sitting down hard, several people arriving at once, and someone standing or jumping on one end. That last case is why the load check includes an end-loaded condition rather than only a distributed one – a load at the end of a bench puts a much higher moment into one leg and its base fixing than the same weight spread across the seat. If your specification has a requirement for a specific test method, send it and the check will be carried out that way.

Send the bench length, the seat height, the slat material you prefer and how the bench will be fixed down. Slat fixing detail and the base arrangement both follow from those answers. Send your specification for a quotation.

Frames and slats are packed together so the drilled fixing positions stay matched to the frame they belong to – see the packaging guide.

A Bench Is Specified by How It Is Anchored, Not by Its Load Figure

300 kg is not a difficult load for a welded steel frame; the frame is not the limiting item and it never has been. What limits a public bench is what it is fixed to and what happens to it when it is not fixed at all. A free-standing bench gets moved, and a bench that gets moved gets dropped on its feet, which is how the feet and the welds at the bottom of the legs fail. A bolted bench does not get moved, but the anchoring has to suit the surface, and a fixing that is correct for concrete is wrong for paving that can be lifted.

• Free-standing feet should be detailed to take a drop onto a hard surface rather than to look slim. This is the part of the frame that gets abused.
• Bolt-down feet need a hole pattern that matches a real anchor, which means knowing the substrate at specification time rather than at installation.
• Seat height and depth are comfort dimensions, and they also decide how much of the load lands on the front edge of the seat. A deeper seat loads the front rail more.

Wood-Plastic Slats Move, and the Frame Has to Let Them

Wood-plastic composite has a much larger coefficient of thermal expansion than steel, and a bench that is assembled in a cold workshop and installed in summer sun will show it. If the slats are fixed with round holes at a fixed pitch with no allowance, they will either bow between fixings or crack at the fixing, and they will do it in the first season. The usual answer is a slotted hole or an oversize hole at one end of each slat so the movement is absorbed rather than resisted.

The second issue is that composite slats hold water at the interface with the steel, and a flat-topped rail under a slat is a permanently damp line. A rail detail that lets water off the top face is worth more than a thicker coating. Tell us whether the slats are supplied by you or by us, because the hole pattern has to be produced to suit the actual slat section, and a pattern taken from a drawing of a different slat is a common source of assembly problems on site. Lead time is quoted after drawing review and process confirmation.

Payment Terms

How a project is paid for is agreed before production starts, and the structure that applies to your order is stated on the quotation and on the order confirmation, so there is no ambiguity later.

• 30% advance payment with the order and the 70% balance before shipment — our standard structure.
• 70% advance payment with the order and the 30% balance before shipment — used for some projects.
• 100% payment in advance before production starts — used for some projects.

If your finance team works to a fixed structure, say so in the first enquiry and we will confirm what applies to your order before you commit. Request a quotation.

Questions buyers ask before sending drawings

The questions that come up most often before a project starts, answered the way we answer them by email.

What do you need from me to quote Park Bench?

2D drawings as PDF, DWG or DXF, or 3D files as STEP, IGES or SolidWorks, together with material grade, sheet thickness, surface finish, quantity and destination country. If the drawing is not finished yet, send a photo, a sketch or the existing part instead — we review what can be measured from it and reply with the questions that still need answering.

How long does a quotation take?

Enquiries are answered within one business day. Simple laser-cut and bent parts are quoted within 24 hours. Welded frames, assembled units and multi-part structures are quoted after the drawing review and process confirmation, and the date is confirmed in our reply.

Is there a minimum order quantity?

Prototypes are made from a single piece and small batches of 10–50 pieces are routine. Prototype, first batch and repeat volume are quoted together so the numbers stay consistent as the project scales.

Can you work from a sample or a photo if I have no drawing?

Yes. Send the part itself, clear photographs with a rule or caliper in frame, or a dimensioned sketch. We measure what can be measured, list what is still undefined, and confirm it with you before production.

Need a Similar Part?

Most enquiries that start on a page like this are not an order for Park Bench — they are a search for a factory that can make something like it. Send us your drawing, 3D model or sample and we will review the manufacturing process and the quotation requirements, then come back with a process plan, a price and a lead time.

We work from 2D drawings, STEP / DWG / DXF / PDF files, or a physical sample if that is all you have.

Trade Terms and Delivery

We quote under the standard Incoterms your logistics team already works with, and build the packing and documentation around the one you choose.

• EXW — you collect from our Ningbo facility and run export clearance through your own forwarder.
• FOB Ningbo — we deliver to the vessel at Ningbo port and handle export clearance.

• DDP — we handle carriage, insurance, import clearance and duties through to your door.

Send your destination country, target delivery date and preferred trade term together with the drawing. Request a quotation.

Quotation Time

We quote from your drawings. How long that takes depends on what the part asks for:

• Simple parts — quoted within 24 hours. Laser-cut blanks and bent components, supplied with complete 2D or 3D drawings. Mon–Fri, GMT+8.
• Complex assemblies — quoted after the drawing review. Payment kiosks, multi-part welded frames, enclosures with purchased hardware, or anything needing a coating or assembly trial. We confirm a quotation date once the scope is clear.

Production lead time is quoted separately, after drawing review and process confirmation. Send your drawings.
