Welded Socket
The Welded Socket is a permanent steel socket welded directly onto a steel beam to provide a fixed insertion point for Combisafe safety posts. Two variants are available: the standard Welded Socket (code 37115, 0.5 kg) for general beam applications, and the Intermediate Flange Socket (code 74415, 2.5 kg) for narrower flange situations where the standard socket profile does not achieve a stable weld. Once welded, the socket accepts a Combisafe safety post and, when paired with a Pre-cast Attachment Sleeve, creates a tamper-resistant connection that resists post withdrawal.
The Welded Socket is specified on steel structures where edge protection post positions are fixed and known in advance. Welding the socket to the beam before the structure is erected allows the posts to be fitted and removed repeatedly at the same locations throughout the construction programme without reinstalling clamps or fixings at each visit. The maintenance-free, zero-moving-part design of the socket also eliminates the inspection items associated with clamp-based scaffold fittings at those locations.
The socket pairs with the Pre-cast Attachment Sleeve on composite structures where the steel beam is subsequently encased in concrete. In those situations, the socket is welded to the beam before the pour, and the sleeve is welded alongside to provide the in-slab locking feature. Altrad Generation supplies both the Welded Socket and the Intermediate Flange Socket across its UK and Ireland branch network.

Frequently asked questions
Q: What is a welded socket in scaffolding?
A: A welded socket in scaffolding is a steel socket that is permanently welded to a structural steel beam to provide a fixed insertion point for safety posts. The Combisafe Welded Socket (code 37115, 0.5 kg) is field-welded to the beam flange and accepts a Combisafe Safety Post directly. When paired with a Pre-cast Attachment Sleeve, the assembly resists post withdrawal and creates a tamper-proof connection. The socket is maintenance-free and requires no moving parts or periodic adjustment.
Q: How is a welded socket different from a pre-cast sleeve?
A: A welded socket is field-welded to an existing steel beam after fabrication, typically where edge protection positions are determined post-design or where temporary works require a fixed post location on the exposed steelwork. A pre-cast attachment sleeve is factory-welded to the beam before a concrete pour, becoming embedded in the slab. The welded socket weighs 0.5 kg (standard) or 2.5 kg (intermediate flange) and sits on the exposed beam surface. The pre-cast sleeve weighs 0.33 kg and is integrated into the concrete.
Q: What is an intermediate flange socket used for?
A: The Intermediate Flange Socket (code 74415, 2.5 kg) is used on steel beams where the flange width is too narrow for the standard Welded Socket weld geometry. Narrow flanges are common on lighter universal beam sections and some column profiles. The intermediate flange variant provides a larger weld area that stabilises the socket on a narrower support, maintaining the load-bearing performance needed for edge protection post applications. The function is the same as the standard Welded Socket, accepting Combisafe Safety Posts and pairing with the Pre-cast Attachment Sleeve.
